The preg_replace() test took 1.2592 seconds.
Each test case ran 20 random code order iterations consisting of 285,132 loops for a total of 5,702,640 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (1.776) milliseconds per 285,132 loops.
- Total difference 35.52 milliseconds for 5,702,640 loops
The iteration variablity for Code 1 was (14.1420) milliseconds and Code 2 was (12.3128) 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']);
