Each test case ran 20 random code order iterations consisting of 213,967 loops for a total of 4,279,340 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (1.294) milliseconds per 213,967 loops.
- Total difference 25.87 milliseconds for 4,279,340 loops
The iteration variablity for Code 1 was (1.7342) milliseconds and Code 2 was (3.2902) milliseconds. The lower and the closer together there values are the more accurate the results are.
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']);
