Historical ResultsBased on (2) saved test runs, The test labeled "strtr()" was (on average) the faster by 0.0153 seconds, (1.947% faster)
The strtr() test took 0.7719 seconds.
The str_replace() test took 0.7872 seconds.
Each test case ran 20 random code order iterations consisting of 205,043 loops for a total of 4,100,850 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.000) milliseconds per 205,043 loops.
- Total difference 15.33 milliseconds for 4,100,850 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']);
