Historical ResultsBased on (2) saved test runs, The test labeled "callback" was (on average) the faster by 0.0003 seconds, (0.039% faster)
The callback test took 0.7713 seconds.
The if test took 0.7716 seconds.
Each test case ran 20 random code order iterations consisting of 205,407 loops for a total of 4,108,140 runs.
- Line execution difference (0.000000) milliseconds.
- Avg difference (0.000) milliseconds per 205,407 loops.
- Total difference 0.30 milliseconds for 4,108,140 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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();
