Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 295,269 loops for a total of 5,905,380 runs.

Line execution difference (0.000001) milliseconds.
Avg difference (0.351) milliseconds per 295,269 loops.
Total difference 7.02 milliseconds for 5,905,380 loops

The iteration variablity for Code 1 was (3.4908) milliseconds and Code 2 was (3.5378) 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);
