Historical ResultsBased on (7) saved test runs, The test labeled "preg_replace()" was (on average) the faster by 0.0255 seconds, (3.333% faster)
The preg_replace() test took 0.7381 seconds.
The stri_replace() test took 0.7636 seconds.
Each test case ran 20 random code order iterations consisting of 170,787 loops for a total of 3,415,740 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (0.000) milliseconds per 170,787 loops.
- Total difference 25.45 milliseconds for 3,415,740 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']);
