Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 139,658 loops for a total of 2,793,160 runs.
- Line execution difference (0.000011) milliseconds.
- Avg difference (1.506) milliseconds per 139,658 loops.
- Total difference 30.12 milliseconds for 2,793,160 loops

Code
The first test, "preg_replace()", was:
$GLOBALS['dummy2'] = preg_replace('~(Wheat|Thins)~i', 'Nilla', $GLOBALS['dummy']);
The second test, "stri_replace()", was:
$GLOBALS['dummy2'] = str_ireplace(array('Wheat', 'Thins'), 'Nilla', $GLOBALS['dummy']);
