Historical Results

Based on (8) saved test runs, The test labeled "strpos()" was (on average) the faster by 0.0064 seconds, (0.892% faster)

strpos() 100%
preg_match() 99.108%

The strpos() test took 0.7137 seconds.
The preg_match() test took 0.7201 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 157,752 loops for a total of 3,155,030 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 157,752 loops.
  • Total difference 6.42 milliseconds for 3,155,030 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, "preg_match()", was:

if (preg_match('~http://([^\./]+\.[^/]+?)/~', $GLOBALS['dummy'], $match) != 0)
	$GLOBALS['dummy2'] = $match[1];

The second test, "strpos()", was:

$pos_start = strpos($GLOBALS['dummy'], 'http://') + strlen('http://');
$pos_slash = strpos($GLOBALS['dummy'], '/', $pos_start + 2);

$pos_dot = strpos($GLOBALS['dummy'], '.', $pos_start + 1);
if ($pos_dot !== null && $pos_dot < $pos_slash)
	$GLOBALS['dummy2'] = substr($GLOBALS['dummy'], $pos_start, $pos_slash - $pos_start);
