Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 121,989 loops for a total of 2,439,780 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.551) milliseconds per 121,989 loops.
- Total difference 11.03 milliseconds for 2,439,780 loops

Code
The first test, "preg_replace()", was:
$GLOBALS['dummy2'] = preg_replace('~([Ww]heat|[Tt]hins)~', 'Nilla', $GLOBALS['dummy']);
The second test, "str_replace()", was:
$GLOBALS['dummy2'] = str_replace(array('Wheat', 'Thins', 'wheat', 'thins'), 'Nilla', $GLOBALS['dummy']);
