Historical Results
Based on (3) saved test runs, The test labeled "no fcall" was (on average) the faster by 0.0047 seconds, (0.525% faster)
The no fcall test took 0.8953 seconds.
The fcall test took 0.9 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 236,389 loops for a total of 4,727,780 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.000) milliseconds per 236,389 loops.
- Total difference 4.73 milliseconds for 4,727,780 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()
{
for ($i = 0; $i < 20; $i++)
$GLOBALS['dummy'] + $i;
}
*/
do_something();
The second test, "no fcall", was:
for ($i = 0; $i < 20; $i++) $GLOBALS['dummy'] + $i;
