Result: Discarded
The test labeled "fcall" was the faster by 0.0422 seconds, (4.679% faster)
The fcall test took 0.8599 seconds.
The callback test took 0.9021 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 196,661 loops for a total of 3,933,220 runs.
- Line execution difference (0.000011) milliseconds.
- Avg difference (2.111) milliseconds per 196,661 loops.
- Total difference 42.21 milliseconds for 3,933,220 loops
The iteration variablity for Code 1 was (4.5029) milliseconds and Code 2 was (5.4923) 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';
