PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: min/max vs. if

No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "ifs" was the faster by 0.0095 seconds, (1.699% faster)

ifs 100%
min()/max() 98.301%

The ifs test took 0.5522 seconds.
The min()/max() test took 0.5617 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 141,723 loops for a total of 2,834,460 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.477) milliseconds per 141,723 loops.
  • Total difference 9.54 milliseconds for 2,834,460 loops

The iteration variablity for Code 1 was (2.4099) milliseconds and Code 2 was (1.3521) 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'];
}
