Historical Results
Based on (2) saved test runs, The test labeled "fcall" was (on average) the faster by 0.0085 seconds, (1.323% faster)
The fcall test took 0.6369 seconds.
The no fcall test took 0.6454 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 141,531 loops for a total of 2,830,620 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 141,531 loops.
- Total difference 8.54 milliseconds for 2,830,620 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;
