The test labeled "fcall" was the faster by 0.0133 seconds, (2.617% faster)
The fcall test took 0.4947 seconds.
The callback test took 0.5079 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 140,195 loops for a total of 2,803,900 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.665) milliseconds per 140,195 loops.
- Total difference 13.29 milliseconds for 2,803,900 loops
The iteration variablity for Code 1 was (0.5274) milliseconds and Code 2 was (1.0070) 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'] + $i; } */ do_something(74);
The second test, "callback", was:
/* function do_something($i) { for ($i = 0; $i < 20; $i++) $GLOBALS['dummy'] + $i; } $GLOBALS['do_something_cb'] = 'do_something'; */ $GLOBALS['do_something_cb'](74);
