PHP: Autoloading Objects Published 28 Feb 2008
Having only relatively recently shifting completely to PHP5 and OO development, there’s a few very useful things that slipped past me. One of these is Autoloading Objects, using a special __autoload function you can include the class file just in time for the first object creation. If you don’t create an instance of a class, you don’t waste resources by having PHP parse code it’s not going to use. What’s more, you can be less mindful of what your including on a given page, you can let autoload take care of it.
require_once $class_name . '.php';
$obj = new MyClass1();
$obj2 = new MyClass2();
