Each test case ran 20 random code order iterations consisting of 128,236 loops for a total of 2,564,720 runs.
- Line execution difference (0.000017) milliseconds.
- Avg difference (2.154) milliseconds per 128,236 loops.
- Total difference 43.08 milliseconds for 2,564,720 loops
The iteration variablity for Code 1 was (5.4027) milliseconds and Code 2 was (5.7728) 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:
