Result: DiscardedThe test labeled "callback" was the faster by 0.1148 seconds, (11.994% faster)
The callback test took 0.8422 seconds.
The if test took 0.9569 seconds.
Each test case ran 20 random code order iterations consisting of 161,911 loops for a total of 3,238,220 runs.
- Line execution difference (0.000035) milliseconds.
- Avg difference (5.739) milliseconds per 161,911 loops.
- Total difference 114.78 milliseconds for 3,238,220 loops
The iteration variablity for Code 1 was (8.4798) milliseconds and Code 2 was (7.0024) 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();
