Historical ResultsBased on (6) saved test runs, The test labeled "strtr()" was (on average) the faster by 0.0148 seconds, (1.578% faster)
The strtr() test took 0.9241 seconds.
The str_replace() test took 0.9389 seconds.
Each test case ran 20 random code order iterations consisting of 247,248 loops for a total of 4,944,963 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 247,248 loops.
- Total difference 14.82 milliseconds for 4,944,963 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.
The first test, "strtr()", was:
strtr($GLOBALS['dummy'], array('string' => 'STRING!'));
The second test, "str_replace()", was:
str_replace('string', 'STRING!', $GLOBALS['dummy']);
