Each test case ran 20 random code order iterations consisting of 277,584 loops for a total of 5,551,680 runs.
- Line execution difference (0.000021) milliseconds.
- Avg difference (5.808) milliseconds per 277,584 loops.
- Total difference 116.16 milliseconds for 5,551,680 loops
The iteration variablity for Code 1 was (11.0085) milliseconds and Code 2 was (6.7756) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "str_ireplace", was:
str_ireplace('sTrIng', 'STRING!', $GLOBALS['dummy']);
The second test, "str_replace/strtolower", was:
