Result: DiscardedThe test labeled "if" was the faster by 0.0046 seconds, (0.438% faster)
The if test took 1.0416 seconds.
The callback test took 1.0462 seconds.
Each test case ran 20 random code order iterations consisting of 246,506 loops for a total of 4,930,120 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.229) milliseconds per 246,506 loops.
- Total difference 4.58 milliseconds for 4,930,120 loops
The iteration variablity for Code 1 was (4.7125) milliseconds and Code 2 was (2.4338) 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();
