Historical Results

Based on (1) saved test runs, The test labeled "callback" was (on average) the faster by 0.0071 seconds, (0.976% faster)

callback 100%
if 99.024%

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';
	$cb = 'do_something2';

The second test, "if", was:

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