Historical ResultsBased on (6) saved test runs, The test labeled "preg_replace()" was (on average) the faster by 0.0168 seconds, (2.138% faster)
The preg_replace() test took 0.771 seconds.
The stri_replace() test took 0.7879 seconds.
Each test case ran 20 random code order iterations consisting of 205,412 loops for a total of 4,108,243 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.000) milliseconds per 205,412 loops.
- Total difference 16.85 milliseconds for 4,108,243 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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('~(Wheat|Thins)~i', 'Nilla', $GLOBALS['dummy']);
The second test, "stri_replace()", was:
$GLOBALS['dummy2'] = str_ireplace(array('Wheat', 'Thins'), 'Nilla', $GLOBALS['dummy']);
