Test: callback vs. call_user_func

No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "callback" was the faster by 0.0257 seconds, (2.654% faster)

callback 100%
call_user_func() 97.346%

The callback test took 0.9419 seconds.
The call_user_func() test took 0.9676 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 257,082 loops for a total of 5,141,640 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (1.284) milliseconds per 257,082 loops.
  • Total difference 25.68 milliseconds for 5,141,640 loops

The iteration variablity for Code 1 was (3.7477) milliseconds and Code 2 was (5.1832) 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);
