Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 159,691 loops for a total of 3,193,820 runs.

  • Line execution difference (0.000000) milliseconds.
  • Avg difference (0.000) milliseconds per 159,691 loops.
  • Total difference 1.20 milliseconds for 3,193,820 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'], $GLOBALS['replacements']);

The second test, "str_replace()/array_keys()", was:

str_replace(array_keys($GLOBALS['replacements']), $GLOBALS['replacements'], $GLOBALS['dummy']);
