Historical ResultsBased on (1) saved test runs, The test labeled "strtr()" was (on average) the faster by 0.0237 seconds, (2.240% faster)
The strtr() test took 1.0361 seconds.
The str_replace() test took 1.0598 seconds.
Each test case ran 20 random code order iterations consisting of 279,340 loops for a total of 5,586,800 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.000) milliseconds per 279,340 loops.
- Total difference 23.74 milliseconds for 5,586,800 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']);
