The strtr() test took 0.7795 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 209,189 loops for a total of 4,183,787 runs.
- Line execution difference (0.000000) milliseconds.
- Avg difference (0.000) milliseconds per 209,189 loops.
- Total difference 1.24 milliseconds for 4,183,787 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']);
