Test: fcall vs. callback

No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "callback" was the faster by 0.0005 seconds, (0.110% faster)

callback 100%
fcall 99.89%

The callback test took 0.4565 seconds.
The fcall test took 0.457 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 53,560 loops for a total of 1,071,200 runs.

  • Line execution difference (0.000000) milliseconds.
  • Avg difference (0.025) milliseconds per 53,560 loops.
  • Total difference 0.50 milliseconds for 1,071,200 loops

The iteration variablity for Code 1 was (3.4726) milliseconds and Code 2 was (4.0457) 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);
