PHP Examples - Autoload

autoload.php

/*
Autoloading is very nifty, and is used in a lot of large frameworks - it allows you to load the file that a class is written in automatically when you try to instantiate it. The advantage of this is that only classes that you want to instantiate & use will be included in your page and will keep memory usage down.
*/

// Using an anonymous function
spl_autoload_register(function($class){
    include_once('includes/' . $class . '.class.php')
});

// Using a named function
function autoload_class($class){
    include_once('includes/' . $class . '.class.php');
}
spl_autoload_register('autoload_class');
