Object overloading in PHP5 :: a programmer's best friend

One of my favourite new features of PHP5 are the object overloading capabilities. These allow you to specify for any of your objects how they should look like as a string. By adding four lines of code to patTemplate, the follwing example is possible:

<?PHP
require_once 'patTemplate.php';
$tmpl = new patTemplate();
$tmpl->readTemplatesFromInput( 'anyTemplate.tmpl' );
$tmpl->addVar( 'page', 'foo', 'bar' );
echo $tmpl;
?>

This will display the rendered template to the browser. I guess this will open a lot of new possibilities for your PHP applications.
