Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 152,146 loops for a total of 3,042,920 runs.

Line execution difference (0.000007) milliseconds.
Avg difference (1.061) milliseconds per 152,146 loops.
Total difference 21.23 milliseconds for 3,042,920 loops

The iteration variablity for Code 1 was (3.4473) milliseconds and Code 2 was (2.1505) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "fcall", was:

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

do_something(74);

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

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

call_user_func('do_something', 74);
