Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 278,506 loops for a total of 5,570,120 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.988) milliseconds per 278,506 loops.
- Total difference 19.75 milliseconds for 5,570,120 loops
The iteration variablity for Code 1 was (7.5547) milliseconds and Code 2 was (7.9222) 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']);
