Result: Discarded

The test labeled "callback" was the faster by 0.1148 seconds, (11.994% faster)

callback 100%
if 88.006%

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';
	$cb = 'do_something2';

The second test, "if", was:

$v = 'do_something1';
if ($GLOBALS['dummy'] === 41)
