Historical Results

Based on (4) saved test runs, The test labeled "fcall" was (on average) the faster by 0.0065 seconds, (1.006% faster)

fcall 100%
callback 98.994%

The fcall test took 0.6441 seconds.
The callback test took 0.6507 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 142,878 loops for a total of 2,857,560 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 142,878 loops.
  • Total difference 6.55 milliseconds for 2,857,560 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, "fcall", was:

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

do_something(74);

The second test, "callback", was:

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

$GLOBALS['do_something_cb'](74);
