Historical Results

Based on (1) saved test runs, The test labeled "callback" was (on average) the faster by 0.0146 seconds, (2.897% faster)

callback 100%
if 97.103%

The callback test took 0.4895 seconds.
The if test took 0.5041 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 130,308 loops for a total of 2,606,160 runs.

  • Line execution difference (0.000006) milliseconds.
  • Avg difference (0.000) milliseconds per 130,308 loops.
  • Total difference 14.60 milliseconds for 2,606,160 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.

Code

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();
