PHP functions tutorial

Below is a brief tutorial on how to use PHP functions. The purpose of functions is to run a series of statements without having to duplicate the code several times. This makes your program neater and easier to interpret.

Here is an example:

<?php

class test {

public function hello() {

echo "hello world";

}

}

$test1 = new test;

$test1->hello();

?>

Your browser should read 'hello world'.
