Result: Discarded
The test labeled "callback" was the faster by 0.0071 seconds, (0.657% faster)
The callback test took 1.0731 seconds.
The fcall test took 1.0802 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 290,012 loops for a total of 5,800,240 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.355) milliseconds per 290,012 loops.
- Total difference 7.10 milliseconds for 5,800,240 loops
The iteration variablity for Code 1 was (3.6949) milliseconds and Code 2 was (3.3571) 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;
}
*/

The second test, "callback", was:
/*
function do_something($i)
{
for ($i = 0; $i < 20; $i++)
$GLOBALS['dummy'] + $i;
}
$GLOBALS['do_something_cb'] = 'do_something';
