Result: SavedThe test labeled "callback" was the faster by 0.0165 seconds, (1.455% faster)
The callback test took 1.1176 seconds.
The if test took 1.1341 seconds.
Each test case ran 20 random code order iterations consisting of 272,933 loops for a total of 5,458,660 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.825) milliseconds per 272,933 loops.
- Total difference 16.50 milliseconds for 5,458,660 loops
The iteration variablity for Code 1 was (5.6783) milliseconds and Code 2 was (5.7725) 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();
