Result: Discarded

The test labeled "eval()" was the faster by 0.0393 seconds, (6.319% faster)

eval() 100%
create_function() 93.681%

The eval() test took 0.582 seconds.
The create_function() test took 0.6212 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 131,730 loops for a total of 2,634,600 runs.

  • Line execution difference (0.000015) milliseconds.
  • Avg difference (1.963) milliseconds per 131,730 loops.
  • Total difference 39.25 milliseconds for 2,634,600 loops

The iteration variablity for Code 1 was (2.3413) milliseconds and Code 2 was (4.1899) 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']();
