Historical ResultsBased on (1) saved test runs, The test labeled "strtr()" was (on average) the faster by 0.0045 seconds, (0.451% faster)
The strtr() test took 0.9934 seconds.
The str_replace()/array_keys() test took 0.9979 seconds.
Each test case ran 20 random code order iterations consisting of 229,322 loops for a total of 4,586,440 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.000) milliseconds per 229,322 loops.
- Total difference 4.50 milliseconds for 4,586,440 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:
The second test, "str_replace()/array_keys()", was:
str_replace(array_keys($GLOBALS['replacements']), $GLOBALS['replacements'], $GLOBALS['dummy']);
