Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 130,673 loops for a total of 2,613,460 runs.

  • Line execution difference (0.000000) milliseconds.
  • Avg difference (0.011) milliseconds per 130,673 loops.
  • Total difference 0.22 milliseconds for 2,613,460 loops

The iteration variablity for Code 1 was (1.2750) milliseconds and Code 2 was (1.4045) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "strtr()", was:

$GLOBALS['i']++;

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

$GLOBALS['asdfasdfasdfjjskljdfklajlsdjfajskldfjkaskjdkfjaskldjfklasjkldfjklasdj']++;
