Result: DiscardedThe test labeled "str_replace()" was the faster by 0.003 seconds, (0.283% faster)
The str_replace() test took 1.0435 seconds.
The preg_replace() test took 1.0464 seconds.
Each test case ran 20 random code order iterations consisting of 278,923 loops for a total of 5,578,460 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.148) milliseconds per 278,923 loops.
- Total difference 2.96 milliseconds for 5,578,460 loops
The iteration variablity for Code 1 was (1.8865) milliseconds and Code 2 was (1.4628) 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']);
