p. This area is intended for everyone new to PHP. It opens with a series of informal, entertaining tutorials written by Vikram Vaswani, founder and CEO of Melonfire. These tutorials build on a previously-published 5-part series which has now been updated and extended to embrace PHP 5, making parts of it suitable for those of you who already have worked with PHP 4 in the past.

p. When you first started reading this series, I promised you that you’d have a whole lot of fun. If you’re the cynical type, you may be feeling that I didn’t keep my promise. After all, how much fun have you really had so far? All you’ve done is learn a bunch of theoretical rules, added and subtracted numbers from each other, learnt primitive decision-making and gone round and round in the circular funhouse of loops. Heck, if this wasn’t a PHP tutorial, it would be kindergarten…I hear you.

PHP 101 (part 13): The Trashman Cometh – Part 1

p. Maybe you’ve heard the term GIGO before.

p. If you haven’t, it stands for Garbage In, Garbage Out, and it’s a basic fact of computer programming: if you feed your program bad input, you’re almost certainly going to get bad output. And no matter which way you cut it, bad output is not a Good Thing for a programmer who wants to get noticed.

In the course of this series, I’ve taken you on a tour of PHP, teaching you everything you need to know to get started with this extremely powerful toolkit. You’ve learned how to process arrays, write functions, construct objects, and throw exceptions. You’ve also learned how to read user input from forms, search databases, and use cookies and sessions to maintain state. You’re no longer the timid PHP newbie you used to be, but a bold and powerful PHP warrior, ready to take on anything the world (or your boss) throws at you…

p. After the workout I gave you last time, you’re probably either chomping at the bit to build another PHP application or you’ve decided to give up PHP programming and try growing cucumbers instead. If it’s the latter, you should stop reading right now, because I can guarantee you that this concluding installment of PHP 101 has absolutely nothing to teach you about vegetable farming.

PHP 101 (part 1): Down the Rabbit Hole

p. If you’re new to Web development, you could be forgiven for thinking that it consists of no more than a mass of acronyms, each one more indecipherable than the last. ASP, CGI, SOAP, XML, HTTP – the list seems never-ending, and the sheer volume of information on each of these can discourage the most avid programmer. But before you put on your running shoes and flee, there’s a little secret you should know. To put together a cutting-edge Web site, chock full of all the latest bells and whistles, there’s only one acronym you really need to know:

p. If you’ve been paying attention, you remember that in Part Two I gave you a quick crash course in PHP’s basic control structures and operators. I also showed you how PHP can be used to process the data entered into a Web form. In this tutorial, I’m going to delve deeper into PHP’s operators and control structures, showing you two new operators, an alternative to the if-else() family of conditional statements, and some of PHP’s more interesting loops.

PHP 101 (part 4): The Food Factor

p. Having spent lots of time travelling around the outer landscape of PHP – learning all about control structures, operators and variables – you’re probably bored. You might even be thinking of dropping out right now, and instead spending your time more constructively (or so you think) in front of the idiot box. That would be a big mistake. And when I say big, I mean humongous.

PHP 101 (part 6): Functionally Yours

p. If you’ve been taking your regular dose of PHP 101, you know now enough about PHP to write simple programs of your own. However, these programs will be “procedural” or linear – the statements in them will be executed sequentially, one after another – simply because that’s the only programming style I’ve used so far.

p. You know what they say about a little knowledge being a dangerous thing… as your PHP scripts become more and more complex, it’s only a matter of time before you bump your head against the constraints of the procedural method, and begin looking for a more efficient way of structuring your PHP programs.
