Test: create_function() vs. func callback

Using a pre-created function, is there any penalty in calling it versus a regular free function using a callback?

Code

The first test, "create_function()", was:

/*
$GLOBALS['dummy'] = create_function('', '
	$x = 0;
	$x += 5;

	if ($x >= 5)
		$x = 0;

	$x;
	$x;');
*/

$GLOBALS['dummy']();

The second test, "regular callback", was:

/*
function dummy()
{
	$x = 0;
	$x += 5;

	if ($x >= 5)
		$x = 0;

	$x;
	$x;
}
$GLOBALS['dummy_cb'] = 'dummy';
*/

$GLOBALS['dummy_cb']();
