Result: Discarded

The test labeled "callback" was the faster by 0.011 seconds, (1.592% faster)

callback 100%
if 98.408%

The callback test took 0.6828 seconds.
The if test took 0.6939 seconds.


Each test case ran 20 random code order iterations consisting of 149,038 loops for a total of 2,980,760 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.552) milliseconds per 149,038 loops.
  • Total difference 11.05 milliseconds for 2,980,760 loops

The iteration variablity for Code 1 was (7.3118) milliseconds and Code 2 was (7.5642) 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)
