Result: DiscardedThe test labeled "if" was the faster by 0.0052 seconds, (0.642% faster)
The if test took 0.8112 seconds.
The callback test took 0.8165 seconds.
Each test case ran 20 random code order iterations consisting of 188,423 loops for a total of 3,768,460 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.262) milliseconds per 188,423 loops.
- Total difference 5.24 milliseconds for 3,768,460 loops
The iteration variablity for Code 1 was (2.5043) milliseconds and Code 2 was (1.1067) 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();
