The strtr() test took 0.6354 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 169,621 loops for a total of 3,392,420 runs.
- Line execution difference (0.000009) milliseconds.
- Avg difference (1.464) milliseconds per 169,621 loops.
- Total difference 29.28 milliseconds for 3,392,420 loops
The iteration variablity for Code 1 was (3.8574) milliseconds and Code 2 was (0.8980) 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']);
