No Description

Historical Results

Based on (2) saved test runs, The test labeled "create_function()" was (on average) the faster by 0.0023 seconds, (0.262% faster)

create_function() 100%

eval() 99.738%

The create_function() test took 0.8894 seconds.
The eval() test took 0.8917 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 211,685 loops for a total of 4,233,700 runs.

Line execution difference (0.000001) milliseconds.
Avg difference (0.000) milliseconds per 211,685 loops.
Total difference 2.33 milliseconds for 4,233,700 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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']();
