Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 115,236 loops for a total of 2,304,720 runs.

Line execution difference (0.000010) milliseconds.
Avg difference (1.119) milliseconds per 115,236 loops.
Total difference 22.37 milliseconds for 2,304,720 loops

The iteration variablity for Code 1 was (0.7626) milliseconds and Code 2 was (1.9487) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

eval('
	$x = 0;
	$x += 5;

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

	$x;
	$x;');

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

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

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

	$x;
	$x;');
$GLOBALS['dummy']();
