Based on (2) saved test runs, The test labeled "strtr()" was (on average) the faster by 0.0085 seconds, (1.184% faster)
The strtr() test took 0.7122 seconds.
The str_replace() test took 0.7207 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 203,312 loops for a total of 4,066,230 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 203,312 loops.
- Total difference 8.54 milliseconds for 4,066,230 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']);
