Historical Results

Based on (1) saved test runs, The test labeled "callback" was (on average) the faster by 0.0096 seconds, (1.200% faster)

callback 100%
wrapped 98.8%

The callback test took 0.7926 seconds.
The wrapped test took 0.8022 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 189,766 loops for a total of 3,795,320 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.000) milliseconds per 189,766 loops.
  • Total difference 9.63 milliseconds for 3,795,320 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, "callback", was:

if ($GLOBALS['dummy'] === 41)
	$cb = 'do_something1';
else
	$cb = 'do_something2';
$cb();

The second test, "wrapped", was:

/*
function do_something($type)
{
	if ($type === 'do_something1')
		do_something1();
	else
		do_something2();
}
*/

if ($GLOBALS['dummy'] == 41)
	$cb = 'do_something1';
else
	$cb = 'do_something2';
do_something($cb);
