Bug description:Missing function to determine refcount of variables directy

Description:
------------
While working on an Entity-Manager Class I noticed PHP has no function
to determine the number of active references to a variable/object (like
debug_zval_dump() does).

It would be great if PHP provided that feature in later versions.






Test script:
---------------
/**
 * function to do the job:
 *
 */
function refcount ($var) {
    ob_start();
    debug_zval_dump($var);
    $zval = ob_get_clean();

    preg_match ("/refcount\\(([0-9]+)\\)/", $zval, $matches);
    return $matches[1];
}
