Result: DiscardedThe test labeled "if" was the faster by 0.1062 seconds, (6.500% faster)
The if test took 1.5275 seconds.
The callback test took 1.6337 seconds.
Each test case ran 20 random code order iterations consisting of 288,764 loops for a total of 5,775,280 runs.
- Line execution difference (0.000018) milliseconds.
- Avg difference (5.310) milliseconds per 288,764 loops.
- Total difference 106.19 milliseconds for 5,775,280 loops
The iteration variablity for Code 1 was (30.6825) milliseconds and Code 2 was (27.8896) 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();
