You can autoload class files using the __autoload() function. Simply define the function with a single argument (this will be the name of the class) .

Code:

function __autoload($szClassName)
{
		$szFilePath = "lib/$szClassName.php";
		
		if (file_exists($szFilePath))
		{
			include_once($szFilePath);
		}
}

Now if you try to instantiate a class that is unknown, PHP will first try to load the class file via the code we setup in the __autoload funciton before throwing a fatal error.
