Historical Results

Based on (2) saved test runs, The test labeled "call_user_func()" was (on average) the faster by 0.0052 seconds, (0.824% faster)

call_user_func() 100%
callback 99.176%

The call_user_func() test took 0.6298 seconds.
The callback test took 0.635 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 159,061 loops for a total of 3,181,210 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 159,061 loops.
  • Total difference 5.23 milliseconds for 3,181,210 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:

/*
function do_something($i)
{
	for ($i = 0; $i < 20; $i++)
		$GLOBALS['dummy'] + $i;
}
*/

$cb = 'do_something';
$cb(74);

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

/*
function do_something($i)
{
	for ($i = 0; $i < 20; $i++)
		$GLOBALS['dummy'] + $i;
}
*/

$cb = 'do_something';
call_user_func($cb, 74);
