Result: Saved

The test labeled "min()/max()" was the faster by 0.0124 seconds, (2.466% faster)

min()/max() 100%
ifs 97.534%

The min()/max() test took 0.489 seconds.
The ifs test took 0.5013 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 133,427 loops for a total of 2,668,540 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.618) milliseconds per 133,427 loops.
  • Total difference 12.36 milliseconds for 2,668,540 loops

The iteration variablity for Code 1 was (0.6908) milliseconds and Code 2 was (0.6766) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "min()/max()", was:

$GLOBALS['dummy'] = 83;
for ($j = 0; $j < 100; $j++)
	$GLOBALS['dummy2'] = min(50, max(20, $GLOBALS['dummy']));

The second test, "ifs", was:

$GLOBALS['dummy'] = 83;
for ($j = 0; $j < 100; $j++)
{
	if ($GLOBALS['dummy'] < 20)
		$GLOBALS['dummy2'] = 20;
	elseif ($GLOBALS['dummy'] > 50)
		$GLOBALS['dummy2'] = 50;
	else
		$GLOBALS['dummy2'] = $GLOBALS['dummy'];
}
