Result: DiscardedThe test labeled "callback" was the faster by 0.011 seconds, (1.592% faster)
The callback test took 0.6828 seconds.
The if test took 0.6939 seconds.
Each test case ran 20 random code order iterations consisting of 149,038 loops for a total of 2,980,760 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.552) milliseconds per 149,038 loops.
- Total difference 11.05 milliseconds for 2,980,760 loops
The iteration variablity for Code 1 was (7.3118) milliseconds and Code 2 was (7.5642) 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();
