Each test case ran 20 random code order iterations consisting of 133,173 loops for a total of 2,663,460 runs.

  • Line execution difference (0.000009) milliseconds.
  • Avg difference (1.224) milliseconds per 133,173 loops.
  • Total difference 24.47 milliseconds for 2,663,460 loops

The iteration variablity for Code 1 was (5.1377) milliseconds and Code 2 was (4.5823) milliseconds. The lower and the closer together there values are the more accurate the results are.


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

$GLOBALS['dummy2'] = urlencode($GLOBALS['dummy']);

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

$GLOBALS['dummy2'] = rawurlencode($GLOBALS['dummy']);
