Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 147,686 loops for a total of 2,953,720 runs.

Line execution difference (0.000007) milliseconds.
Avg difference (0.963) milliseconds per 147,686 loops.
Total difference 19.27 milliseconds for 2,953,720 loops

The iteration variablity for Code 1 was (3.2498) milliseconds and Code 2 was (3.9806) 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);
