PHP Basics You should already know: HTML, CSS and JavaScript First off, you cannot write and run PHP scripts from Zetaboards or simply from the browser like you would JavaScript. You either need some installation of an Apache Web Server with PHP installed to test your scripts on or better yet some web hosting from which to conduct your scripts. The are some free web hosting which offer both PHP and MySQL 000webhost.com is not a bad start. I've used both 000webhost.com and freehostia.com which is my favourite. You can of course shell out a little cash for much better services. I use 34sp.com which is a great UK web hosting company with a great support service. With that said lets get on. What can PHP do in terms of Zetaboards Mods? The benefit of PHP is that it can run things off of the forum and can do so whenever it is called. It can also help to store information that can be accessed by all. JavaScript is good but it only runs off of the information given to it in a client setting. Because PHP is server side is can give and get information from everyone. Lets get going! Ok so first step is to create a PHP file. Simply create a new file and call it "mytest.php". The .php file extension tells the software that this is a PHP script and will therefore treat it like one. Inside a PHP file we can add HTML, CSS, JavaScript and PHP. A simple PHP script might look like this This would display a page with a paragraph saying "Hello world!". PHP has similar constructs to other programming languages such as variables, loops, arrays, in built functions. It also can be OO (Object Oriented). This means that you can create classes which holds values and performs certain functions. Classes are the in depth description of what an object is. And Object is something that has been created using the class of that object. For example: The first section defines the class test and the last two lines creates the variable $test and creates the object of the class test to that variable (In fact it only assigns a reference to the variable, a reference which accesses the object). We then see in the last line that the variable now can be used to call the methods from the test object, in this case the helloWorld() method, which prints "hello world!" to the page. Note: All PHP variables are prepended by a $. They don't need to be declared before hand and can change type dynamically. e.g. If you call $a at the last line you have a boolean variable. To end with, here are some basic features of PHP that you might find helpful: For loop: Foreach loop: While loop: Arrays: Multidimensional Arrays:
