safe this to the folder with others class with name "class.class_name.php'
then you can do like bellow

$c1 = $di->class_x; //singleton
$c2 = $di->class_x; //singleton
$c3 = $di->class_x(); //not singleton

//PHP5 only
class fuselogic_container
{
   var $__x = array();

function __construct($path = null)
