Historical ResultsBased on (1) saved test runs, The test labeled "callback" was (on average) the faster by 0.0071 seconds, (0.976% faster)
The callback test took 0.7157 seconds.
The if test took 0.7228 seconds.
Each test case ran 20 random code order iterations consisting of 201,479 loops for a total of 4,029,580 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 201,479 loops.
- Total difference 7.05 milliseconds for 4,029,580 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();
