Result: Discarded

The test labeled "strpos()" was the faster by 0.0733 seconds, (6.109% faster)

strpos() 100%

preg_match() 93.891%

The strpos() test took 1.127 seconds.
The preg_match() test took 1.2003 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 282,254 loops for a total of 5,645,080 runs.

Line execution difference (0.000013) milliseconds.
Avg difference (3.667) milliseconds per 282,254 loops.
Total difference 73.33 milliseconds for 5,645,080 loops

The iteration variablity for Code 1 was (6.2556) milliseconds and Code 2 was (4.5804) 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);
