Result: DiscardedThe test labeled "callback" was the faster by 0.0209 seconds, (1.833% faster)
The callback test took 1.1174 seconds.
The if test took 1.1382 seconds.
Each test case ran 20 random code order iterations consisting of 283,446 loops for a total of 5,668,920 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (1.043) milliseconds per 283,446 loops.
- Total difference 20.86 milliseconds for 5,668,920 loops
The iteration variablity for Code 1 was (2.8170) milliseconds and Code 2 was (3.4320) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "callback", was:
if ($GLOBALS['dummy'] === 41) $cb = 'do_something1'; else $cb = 'do_something2'; $cb();
The second test, "if", was:
$v = 'do_something1'; if ($GLOBALS['dummy'] === 41) do_something1(); else do_something2();
