No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "callback" was the faster by 0.0209 seconds, (1.833% faster)

callback 100%
if 98.167%

The callback test took 1.1174 seconds.
The if test took 1.1382 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 283,446 loops for a total of 5,668,920 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (1.043) milliseconds per 283,446 loops.
  • Total difference 20.86 milliseconds for 5,668,920 loops

The iteration variablity for Code 1 was (2.8170) milliseconds and Code 2 was (3.4320) 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();
