How SHOULD developers answer questions?

10/27/2009 7:30pm

A natural continuation from my last post How do GOOD Developers Ask Questions?: How do good developers answer questions? When given a very specific question that you know has a very specific answer, your first reaction might be to blurt out the answer and be done with it. However, I like to go the extra step and ask what they've tried so far or what research they've done. I like to show them how to arive at the answer on their own as well as provide the solution. The old 'Give a man a fish and he eats for a day, teach him to fish and he eats for a lifetime.' Allowing one to do personal research leads to an infinite amount of additional knowledge compared to spoon-feeding code to others.

Ofcourse this doesn't apply to simple quick-reference type questions where you know full-well that the asker is capable of finding the solution on their own but are asking you to save time. AVOID PISSING OFF THE ASKER BY BEING CONDESCENDING OR ANNOYING.

How Do GOOD Developers Ask Questions?

10/7/2009 11:30am

I spend a lot of time on stackoverflow.com and I've seen my fair share of questions. Some good, others leave you wondering how the hell some people made it this far. Good developers have learned how to ask questions to get the best possible answer in the shortest amount of time.

First of all, let me say this. If you consider yourself a developer and don't find yourself wanting to ask questions on a daily basis, you're doing something wrong. Asking questions without being afraid of humiliating yourself is critical.

Let me throw out a few pointers that I've gathered from reading hundreds (if not thousands) of different questions on sites like stackoverflow, experts-exchange, and other various forum-type sites.

Wildflower CMS and Unterminated String Literal Error

3/23/2009 8:00pm

I've been developing a site using Wildflower CMS developed using CakePHP and ran into an infuriating problem. After working on it for several weeks without issue I started receiving javascript errors that caused everything to come to a grinding halt. The errors were all reported using Firebug and the javascript debugger. The culprit:

Unterminated String Literal

After that in the Firebug console was:

$ is not defined

I knew there was a strong possibility that the first error was somehow causing the second and that top-down debugging was the way to go. After inspecting the javascript code I discovered that there was a variable assignment going on that spanned several lines. This might be legal in PHP but not javascript.

Taking a ride down the sunshine highway

3/3/2009 5:00pm

I just wanted to let everyone know that there is a big change coming up in my life. After much thought, discussion, and stress I have decided to leave New City Media. I've lived here in Blacksburg, VA for nearly six years and worked at NCM for two of them. The family-like-culture, environment, and surroundings made this a nearly impossible decision to make. I had the opportunity to work with industries in nearly every walk of life. From small family-owned companies to billion-dollar corporations. Tourism, real-estate, jewelery, industrial manufacturing, education, world-wide non-profits, biotechnology, New City Media gave me the opportunity to be a part of all of these.

I have accepted an offer to join the NFi Studios Interactive Team. NFi develops and maintains several products including MemberFuse. They are located in downtown Orlando, FL which means I will be making my triumphant return to the sunshine state. I spent 9 years in Jacksonville, Florida before moving up here to Appalachia. The office environment and culture at NFi appears to be very relaxed and informal, much like NCM.

I'm excited to be working with web-application type projects. NFi uses the Zend Framework for their enterprise applications. I had the opportunity to take a peak under the hood of one of their projects and was blown away by the quality of their work. I can't wait to get down there and join the team.

Working for New City Media has left me tainted. I've come to realize that I will never be able to work for Corporate-America because of the environment that David Poteet, president NCM, has developed. The first thing I found myself asking companies about was their office environment. Everyone here has been wonderful to me in good times and bad, and I will never forget these last two years.

I'll be moving to Orlando (east side) this weekend and can't wait to jump into the geek-community.

If anyone has any tips, suggestions, or interesting tidbits about the area, happenings, or anything else you think would be useful for my situation please share them.

Zend Certified!

2/9/2009 4:00pm

I passed the Zend PHP5 Certification Exam last week and thought I would share my experience with it.

Zend Yellow Pages

I decided that I wanted to take the test about 2 1/2 months ago. The first thing I did was visit the site and learn more about the exam itself. I discovered it covers almost every facet of the language and its use. Here is a breakdown of the major sections:

PHP Basics
Functions
Arrays
Object Oriented Programming
Security
XML & Web Services
Strings & Patterns
Databases & SQL
Web Features
Streams & Network Programming
PHP 4/5 Differences
Design & Theory

You can get a more details topic list for each section on the PHP5 Certification Landing Page.

For the first month I spent time reading e-books and other free material on the subjects mentioned above that I felt weak in. I was not very devoted during the first month and only spent a couple hours (3-5) each week.

At the beginning of the second month, I purchased two books recommended by a lot of others who passed the exam.

Zend PHP Certification Study Guide - Zend Technologies

The first book is published by Zend and is 'the official study guide to prepare for the Zend PHP Certification exam'. I liked this book because it was very focused and clear about the topics it was covering. It also has a couple of practice questions at the end of each chapter to prepare you for the real thing.

There is also a glossary of terms that help you become familiar with some of the terminology used. Not sure what a HEREDOC or MTA is? Look it up quickly with this book.

This book does have a few technical errors in some examples that you do need to watch out for.

Zend PHP Certification Study Guide 2nd Edition - Davey Safik and Ben Ramsey

I actually started reading this book first. This book contains more information about each topic but seems less focused. What I mean is that the major topics are covered and explained fairly well but it doesn't go as in-depth when it comes to sub-topics. I frequently caught myself going to this book when I needed more general information about something but tended to stay with the aforementioned book because it helped me stay focused.

This book does not contain any practice questions or glossary, which is a bummer.

Zend PHP 5 Certification Online Practice Testing

My last resource was the online practice tests made available Zend. They are in the same format as the real test: 70 questions with a 90 minute timer. The layout of the actual test is a little different than these practice tests but nothing significant. The advantage to these practice tests is that you can go on past the 90 minutes and it will give you two scores. One when the time expired and the other is based on the final submission.

It's important to note that the practice tests do not tell you how you did on each question. Rather it breaks the test down into each major section and gives you one of three scores - fail, pass, or passed with flying colors. I found this to be very annoying but understood the intended benefit.

I took a total of 5 exams out of the 10 that I purchased. After the 5th exam a significant number of questions were repeats which really took away from the 'fear' and 'anxiety' factor of the test. I heavily recommend you take the test until you pass with flying colors in each major section to be ready for the real thing.

Overview

It's been mentioned before and I agree that none of these resources alone are enough to make you feel confident going into the test. Rather, a combination of each resource should be taken advantage of to feel fully prepared. I took every practice question in Zend's book twice and read the entire book two or three times total. I spent a good deal of time in PHP Architect's book but probably only read it front-to-back once.

I consider the practice test to be the most beneficial. I took one test almost immediately after I purchased them to have a baseline benchmark. With a general idea of where I stood in each section I was able to concentrate my studying in those sections. After I was satisfied that I had improved I retook the test and repeated the process until I passed every section with flying colors.

Even with this I still considered the real test to be difficult. The practice test claims to be generally harder than the exam - In my opinion, this is not true.

The style of questions was very test-like. They were very obscure blocks of code that obviously had no real-world use but still covered several very important concepts. There are four types of questions:

Single choice questions - Multiple choice, choose one
Multiple choice questions - Multiple choice, choose several
Fill in the blank questions - Several blanks in a sentence, choose from multiple possible answers
Open questions - fill in the blank (text input)

Test Day!

The test was observed by a proctor at a Pearson Vue testing center of my choice. They took all my belongings and stored them in a secure area (unlocked closet), sat me down in front of a computer, and gave me a laminated sheet of legal-length paper with a dry-erase marker (no eraser, although I'm sure I could have asked for one). The proctor starts the exam and after a few screens explaining the rules, agreeing to a NDA, andmaking sure I was ready, the test began.

I can't really talk much about the test or specific questions that were asked but I can say that they were from every topic. A good variety of mixed-up questions. I don't believe it was the type of test where the questions adjusted themselves based on whether or not you answered correctly or not. It is important to note that there are trick questions.

I found these questions in the book, practice exam, and the exam itself. There would be large blocks of code that would never get executed because of some small detail. I don't believe they are intended to be tricky just for the sake of amusing the test-authors, rather to see if you really pay attention to details in the code. I think we can all agree that attention to detail is of utmost importance in this profession.

Once you have completed all 70 questions you are presented with a chance to go back to any particular question and re-evaluate your answer. Once you're satisfied with your performance you submit the test for grading. After a couple seconds (seemed like days) of plugging and chugging you get a screen with either Pass or Fail. The proctor hands you a printed certificate with your candidate number, grade, and sends you on your way.

Tough Subjects

These were the toughest subjects for me because I do not use them very often:

Bitwise operators.
Data Types
XML & Web Services.
Type Hinting
Database topics - PDO, mysqli, transactions, and other database technologies.
A lot of functions. I had to memorize a lot of functions that I forgot about or used often yet never seemed to remember the parameter order or particular definition. I've become conditioned to pull up the PHP manual and look something up in my sleep. The function you need to know pulled from every corner of PHP. Strings, arrays, files, and network streams just to name a few.
Nuances of PHP's variable juggling.
And more!

Conclusion

I spent a lot of time studying at my leisure but really buckled down the last two weeks leading up to the exam. As I said before, none of the resources I found are enough to make you feelconfident going into the test. Rather, all of them together do a nice job preparing you. There are a lot of questions on subjects that you probably have never used in the past and may never use in the future. I recommend spending some extra time as you may have to memorize several key functions and their parameters for the exam.

I'm glad I spent the time and effort to earn the certification. I know that there are those out there who question its usefulness but I found it extremely helpful. Not only do I find myself more confident in my abilities to use the language properly, but I get to use the Zend logo on my site :)

Feedburner - Account Moving Headaches

2/3/2009 9:00am

So, if you didn't know already, I use Feedburner for my article feeds. They have a lot of really awesome features and I have been happy with their service thus far. A year or two ago, Google boughtFeedburner and provided everyone free upgrades to their 'Pro' package. However, just recently they started migrating the Feedburner accounts to Google. This means your feeds would be associated with your Google account and you could login with the same username/password as you use to get into Gmail or Google Docs.

I signed in last night for the first time in a while and was prompted with a request to go ahead and perform the migration. I didn't see any downside so I went ahead and clicked Yes. The next screen informed me this would take a few minutes and that I would receive an email when it was finished. Sure enough, about five minutes later I got the email. I signed back intoFeedburner with my Google account info and everything looked like it was moved successfully. I had roughly the same number of subscribers and all my settings were the same. The only noticeable difference was my account name changed to my Google username.

Pretty cool, everything seemed to be ok - not that I expected anything different from Google. However, I decided to check my RSS Reader before heading off to bed and discovered that every single one of my articles was there waiting for me (I subscribe to my own feed just to make sure that it's working properly). How could this be? Would everyone get all my articles in their reader again like it was brand new? Sure enough, some sites whichaggregate my feed into a super-feed were also showing all my of articles.

So to everyone who got ~34 new items in their feed because of me - Sorry. I'm not sure if this is my fault or what happened but I just wanted to forwarn everyone before they upgrade.

PHP Data Types - Octal Notation

2/1/2009 2:30pm

I just ran into an interesting question while studying for the Zend certification, and I thought I would share because I was very confused.

What is the output of the following:

<?php $a = 010; $b = 0xA; $c = 2; print $a + $b + $c; ?>

Design Patterns - An Introduction

1/27/2009 9:00am

Over the next couple weeks I'm going to be writing a series on programming design patterns and their applications. I plan to cover the popular patterns as well as the lesser-known, yet still insanely useful, ones too. This first article will go over the background and basics of a design pattern - What they are, why you should care, and how to implement one into your application.

Design Patterns - The Singleton

1/27/2009 9:00am

Often one of the first patterns that young developers encounter, the singleton solves a very sloppy, dangerous, and nightmarish practice known as global variables. There are components in nearly every application that need to be accessed everywhere. Configuration variables are a perfect example of this. The younger developers might be tempted to declare a debug variable as global, and just access it where he/she pleases. You will learn later on in the project that this makes maintaining the application very frustrating.

Code Refactoring - Freaking Awesome

1/2/2009 12:00pm

We have all gone back and looked at code we wrote in the past and thought "Wow, this is ugly.", or "wtf was I thinking?", or even "I wrote this yesterday, and I have no idea what it does." Refactoring is the process of going back over already-working code and cleaning it up for the sole purpose of understandability, maintainability, and preserving your self-worth if anyone else were to take a peak. No one likes to be humiliated by their own code.

CakePHP - Web Test Cases with SimpleTest

12/10/2008 12:00pm

I have fallen in love with CakePHP's integration of the SimpleTest libraries. With the type of work that I normally do, unit-testing is hard to utilize successfully. That is to say, most of the applications I work on have very straight-forward components and not a lot of complex functions/methods. I would only be testing whether or not they worked at all, rather than if they worked in a wide-array of situations.

For example, unit-testing a simple news list and detail page is probably overkill. Sure, you can test your classes by simple instantiating them but that only goes so far. My new method involves using SimpleTest's Scriptable Browser to actually crawl webpages and ensure that the proper data is being displayed. That way, I can catch all my php errors, including notices and warnings, insure that the proper headers are being sent, and assert that certain text is appearing on the page. Unit-testing will rarely catch a poorly coded method that throws a PHP notice whereas the Scriptable Browser will.

CakePHP - Changing the Default Value of a Date-Time Input

12/8/2008 11:30am

Automagically generated date/time input fields normally default to the current date and time. For a couple of reasons, I had to change this to another default value. For example's sake, let's say I needed a time field to always select 1:30 pm in an add action.

Run of the mill example:

<?php echo $form->input('start_dt'); ?>

This will output 3 select boxes; one for hours, minutes, and the merdian (am/pm) with the current time pre-selected. So if it was 3:04 pm, that would be selected.

So lets change this so that 1:30 pm is always pre-selected:

<?php echo $form->input('start_dt', array('selected' => array('hour' => '1', 'minute' => '30', 'meridian' => 'pm') ) ); ?>

That's all there is to it! Cake's automagic owns. Hope this helps someone else :)

MVC - Fat Models and Skinny Controllers

12/5/2008 6:00pm

I've been doing a lot of work with CakePHP lately and it has been amazingly satisfying developing in a framework that encourages great coding practices. More on CakePHP, specifically, later. Right now, I'd like to present some things I've learned about the architecture that CakePHP is built on. I'm talking about the Model-View-Controller (MVC) architecture of course.

I'm hoping most of you reading know already know a thing or two about MVC but if you don't, here is a quick overview from wikipedia.

Model-view-controller (MVC) is an architectural pattern used in software engineering. Successful use of the pattern isolates business logic from user interface considerations, resulting in an application where it is easier to modify either the visual appearance of the application or the underlying business rules without affecting the other. In MVC, the model represents the information (the data) of the application and the business rules used to manipulate the data; the view corresponds to elements of the user interface such as text, checkbox items, and so forth; and the controller manages details involving the communication to the model of user actions such as keystrokes and mouse movements.

My PHP Best Practices

10/7/2008 12:00pm

PHP's greatest strength is also its greatest weakness. Flexibility. There are an infinite number of ways to perform the same task which PHP will happily do without so much as a peep as to how poor the code really is. Sadly, most developers endure a trial by fire where they only learn from their mistakes after it's too late.

I suggest a more retro-active apprach. Studying, surrounding, and forcing yourself to abide by best-practice coding standards will yield surprising results in your applications despite the fact that it may seem like more work than it's worth.

I've come up with a list of things that I feel are most important to me when it comes to coding. So, without further adieu:

Things I Hate - People Who Do-Not Know How to Report Bugs

10/1/2008 1:00pm

Bugs are an inevitable part of any development project that most people loath or at least generally dislike. If you take the time to examine this phase of a project you will find that it's not the bugs that really irk you, but the way they are presented, described, and handled.

Ok, so maybe bugs are not the worst part about my job but they can be very effective at frustrating the hell out of me. After you get over the fact that you are not the world's greatest programmer and are indeed as fallible as the rest of us, you can begin to look at bug reports as an opportunity to better yourself. Learning from your mistakes is a huge part of the job and can be extremely beneficial. However, no matter how vetted any particular programmer may be, most will cringe when they see a bug drop into their inbox.

Installing Bad Behavior Generic - Anti-Spam Solution

7/28/2008 12:00pm

Site spam sucks, no doubt about it. I was getting tired of fighting it manually in hand-to-hand combat and decided to get some help. I'd heard about different techniques for thwarting comment, and other types of form, spam but none of them seemed to make a big enough dent in the problem for my liking. That is, until I tried Bad Behavior.

Egoless Programming - Developing Without the Attitude

7/15/2008 12:00am

One of the most common threads that all programmers share is that of an ego. Some are much worse than others and some have found a way to control or manipulate their ego into a great benefit. Beyond skill-sets and other programming-specific talents I believe the greatest room for personal improvement in programmers as a whole is that of the ego.

A quote by GeraldWeinberg from The Psychology Of Computer Programming.

The idea is that programmers must fight the natural tendency to treat their programs as part of themselves, and therefore to reject all criticism. Rather, they should do their best to treat their designs & implementations as objects independent of themselves, and to view criticism dispassionately on its merits. It's a spiritual discipline that we all fall short of, but that's worth attempting.

Installing Xdebug - Best Decision You Will Ever Make

7/1/2008 9:00am

I finally got around to installing xdebug on my development environment and have decided it is the best thing since sliced bread.Installation was a breeze and the information it provides when something has gone wrong is incredibly helpful during debugging. What I didn't know, and hope to help others by documenting it here, was the amount of configuration options Xdebug has. The base install has some irritating limitations that are easily addressed with a few simple lines in the php.ini file.

PHP - Opening and Saving Files over FTP

6/25/2008 6:00pm

PHP makes file system manipulation easy with its variety of built-in functions. One thing I always knew, but never got the chance to try, is that many of those same functions worked over FTP instead of the local file system. I finally got my excuse to give it the ole' college try and I found a few things that may help others with the same task.

The Ternary Operator

6/23/2008 12:00pm

Every good programmer should constantly be looking for ways to improve the look and readability of their code. One of my favorite ways to reduce vertical length while maintaining readability is to use the lesser-known ternary comparison operator.

The Ternary Operator is unique when it comes to PHP's available comparison options. Not in the sense that it does something that the other operators don't, but that the functionality it offers is not seen anywhere else.

<?php $myvar = ($x == $y) ? TRUE : FALSE; ?>

Caching PHP Pages with Output Buffering

6/18/2008 12:00pm

Noticing your pages are loading slowly or just don't like using extra cpu cycles when you don't have to? PHP makes caching very easy with their variety of Output Control Functions. In this article I'll go over complete page caching which is the easiest to implement and understand.

Setting-Up a Relational Database in MySQL

6/17/2008 10:30am

Relational Database Design is one of the most powerful ways to ensure data integrity and a great way to kick-off any project. Very often the first thing developers do when starting a new project, or stub-project, is to design the database. This way the structure of the application is already in place and we just have to fill in the pieces with some server-side code. I've found when adding relational constraints to your database design you add in a very powerful error reporting tool that will let you know during the development process that you have allowed something to happen that shouldn't have. In this article, I go through, step by step, showing how to set up a simple relational database and discuss the benefits that are enjoyed.

Adding Virtual Hosts to Apache & Wampserver

6/15/2008 9:00am

Being able to develop on my local machine with urls like htto://testsite/index.php has been a godsend. Mostly because I am able to take full advantage of the document root. If I were to develop on something like http://localhost/testsite/index.php I would be extremely limited and forced to used relative urls. In this article I've listed the steps in order to enable this functionality in a wamp server environment.

How fast can you spot PHP Bugs?

6/14/2008 10:00pm

Blake over at PHP vs .NET has written up a very nice article to prepare those who are interviewing for a php job soon. He basically gives a bunch of php snippets and asks where the bugs are. The article somewhat morphs into a mish-mash of good-practice/bad-practice comparison and explains why one way is better than the other.

From the article:

Find the errors in the following code:

<?php function baz($y $z) { $x = new Array(); $x[sales] = 60; $x[profit] = 20: foreach($x as $key = $value) { echo $key+" \"+$value+\"<BR>\"; } } ?>

MySQL - InnoDB vs MyISAM

6/14/2008 7:00pm

Most people who use MySQL know that MyISAM and InnoDB are the two most-common database engines available with the popular opensource datbase provider. I would be that most of those people don't even take the time to select a storage-engine and just accept the database default. Those of you who are left probably heard from a friend who saw something online that said one of the two is better than the other. Those of you who are left will still probably learn a thing or two here :)

Image Styles Not Working in TinyMCE?

6/14/2008 1:00pm

I had an issue lately where image styles that I inputted through TinyMCE weren't working. For example, my images would not align right or left, my borders weren't appearing, and even padding wasn't working. I checked the HTML source and found that no styles at all were making it from the popup Image Dialog to the editor!

Funny Names for ASCII Symbols

6/14/2008 10:00am

Coding Horror has a pretty amusing article on the infinite number of names programmers give common ascii symbols. $, %, &, |, etc are seen across a lot of languages but somehow they have accumulated more names than the entire ascii library combined.

Optimization - PHP Benchmarks

6/10/2008 8:00am

A lot of the gripes about PHP as a language come down to the fact that there are a million ways to accomplish the same task, but only a couple are truely 'correct' - as in significantly better for one reason or another. Out of all those reasons script efficiency and speed are the driving force behind all experienced programmers. That being said it's hard to know what the right way to do things are. Sure there are 100 ways to do something but all but 2 or 3 of those take an obscene amount of time. Normally, during development, you won't notice long load times because it's not getting hammered by thousands of users requesting the same page.

Chris Vincent has set up The PHP Benchmark to help visually show how some methods are more effecient than others.

PHPBench.com was constructed as a way to open people's eyes to the fact that not every PHP code snippet will run at the same speed.

A few highlights:

<?php foreach($aHash as $val); // VS while(list(,$val) = each($aHash)); ?>

foreach($array as $value) is the fastest way to loop through an array.
foreach($array as $key => $value) is slightly slower by about 10-15% so use it only when necassary.
Using while() and for() loops dramatically increases the server load especially when used in conjuction with list() and each().

Making Your Tables Easier on the Eyes

9/11/2007 8:00am

Richard O'Neill has written a short article on improving user-interface by polishing-up your grids and tables. By making a few simple modifications your information can be easily read and understood.

"It's not hard making interfaces look professional. I've found that some good looking icons and a bit of cell padding makes all the difference.
Using the example below, we can apply small changes to the design which will improve usability and make this ugly interface look a lot better."

Creating a Users Online Script using PHP

9/10/2007 8:00am

Creating a way to show how many users are currently visiting your website has become a fad amongst webmasters. It's a cool way to show off your skills has a coder and to show your visitors how many other people are looking at the same thing they are. You don't want to miss the bandwagon again do you? This script is also an excuse to brush up on some mildly advanced MySQL queries.

Making Magic with .htaccess Files

9/9/2007 8:00am

.htaccess files are one of the most underused and underrated forms of web development. They are very easily overlooked or dismissed as unimportant by the amateur programmer. The reality of it is that .htaccess has some of the coolest and ridiculously easy features to offer.

Creating a Simple Registration Script using PHP

9/8/2007 8:00am

The most useful and almost necessary feature of any interactive website is a registration form. A way to give users access to features while keeping out the riff-raff. While a registration script can be the perfect time for an amateur to grab the bull by the horns it can also leave lots of pitfalls for a more experienced programmer.

Creating Static RSS Feeds

9/7/2007 8:00am

Providing RSS Feeds for your website is fast becoming a necessity in today's web2.0 world. The amount of surfers taking advantage of everything RSS Feeds has to offer has exploded in recent history, and it's easy to see why. The amount gained from offering a RSS Feed far outweigh the effort needed to create one.

Using PayPal in your Site - Easier than you Think

9/5/2007 8:00am

Integrating PayPal into your site may seem intimidating to those who have never put together a serious project before. It might seem like everything changes when you start dealing with money. You always hear about someone else who has been scammed or in some kind of nightmare involving some sort of online transaction. When you realize how easy PayPal makes it to utilize their services it really puts any anxiety you have to rest.

How to Create a Simple PHP Text Counter

9/4/2007 8:00am

After learning the basics of PHP's basic file system functions, the first thing you'll want to do is put it to use. One of the easiest and flashiest things you can create is a page counting script. I'll show you how to create a page hit script that is easy to create and even easier to implement.

PHP Cookies vs Sessions - The Breakdown

9/3/2007 8:00am

Knowing the basics of cookies and sessions is essential to any successful PHP programmer. It is useful to store pieces information on the users computer for later use. Things like when they laste visited, language of choice, age, etc. Cookies and Sessions are the perfect solution to our needs.

Browser needs Cookies Enabled?

Can User Edit Information?

Information Lasts Between Browser Sessions?

(Leaving site and coming back)

Information Location

Cookies

Yes

Yes, easily

Yes

User's Browser

Sessions

No*

Server, except for session ID

Using PHP to Access Files - The Basics

9/2/2007 8:00am

The first thing I wanted to know after learning the basics of PHP was how to store my data on a more permanent basis. PHP is all well and good but without the ability to store data between browser sessions it has limited functionality. After learning how to store and retrieve data, your PHP scripts really come to life.

Making your MySQL Tables More Effecient by Using Correct Fieldtypes

9/1/2007 8:00am

One of the biggest mistakes of today's fledgling MySQL programmers is their field type definitions, also known as data type or column type. Many are too quick to set up their tables, flying through the different options without giving it much thought. The time you spend setting up your tables will save you from many headaches later on down the road.
