Result: Discarded
The test labeled "preg_match()" was the faster by 0.0819 seconds, (8.708% faster)
The preg_match() test took 0.8585 seconds.
The strpos() test took 0.9404 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 222,568 loops for a total of 4,451,360 runs.
- Line execution difference (0.000018) milliseconds.
- Avg difference (4.094) milliseconds per 222,568 loops.
- Total difference 81.88 milliseconds for 4,451,360 loops
The iteration variablity for Code 1 was (5.8520) milliseconds and Code 2 was (9.6111) 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);
