Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 214,177 loops for a total of 4,283,549 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 214,177 loops.
- Total difference 12.27 milliseconds for 4,283,549 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.
Code
The first test, "strtr()", was:
strtr($GLOBALS['dummy'], array('string' => 'STRING!'));
The second test, "str_replace()", was:
str_replace('string', 'STRING!', $GLOBALS['dummy']);
