Historical Results
Based on (3) saved test runs, The test labeled "fcall" was (on average) the faster by 0.0313 seconds, (3.866% faster)
The fcall test took 0.7789 seconds.
The no fcall test took 0.8102 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 202,777 loops for a total of 4,055,547 runs.
- Line execution difference (0.000008) milliseconds.
- Avg difference (0.000) milliseconds per 202,777 loops.
- Total difference 31.32 milliseconds for 4,055,547 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;
