Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 284,215 loops for a total of 5,684,300 runs.
- Line execution difference (0.000028) milliseconds.
- Avg difference (7.930) milliseconds per 284,215 loops.
- Total difference 158.61 milliseconds for 5,684,300 loops
The iteration variablity for Code 1 was (5.8270) milliseconds and Code 2 was (7.3981) milliseconds. The lower and the closer together there values are the more accurate the results are.
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']);
