The test labeled "callback" was the faster by 0.0165 seconds, (1.455% faster)

callback 100%
if 98.545%

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';
	$cb = 'do_something2';

The second test, "if", was:

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