preg_match() 98.145%

The strpos() test took 0.6618 seconds.
The preg_match() test took 0.6743 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 175,127 loops for a total of 3,502,540 runs.

Line execution difference (0.000004) milliseconds.
Avg difference (0.626) milliseconds per 175,127 loops.
Total difference 12.51 milliseconds for 3,502,540 loops

The iteration variablity for Code 1 was (1.5159) milliseconds and Code 2 was (0.9732) 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);
