Loading PHP classes from string

Question

I'm looking for a way to load classes into PHP without using hardwired names.

The idea is the script will load a text file with names of 'components'(classes), then load them by the names in the file. For example:

<xml><Classes><class name="myClass"/></Classes></xml>

When the PHP is run, it would need to do something like this:

require_once {myClass}".class.php";
var myclass = new {myClass}();

Answer 1

require_once $class . ".class.php";
$myclass = new $class;
