Result: Discarded

The test labeled "rawurlencode()" was the faster by 0.0248 seconds, (2.359% faster)

rawurlencode() 100%
urlencode() 97.641%

The rawurlencode() test took 1.0271 seconds.
The urlencode() test took 1.0519 seconds.


Each test case ran 20 random code order iterations consisting of 285,521 loops for a total of 5,710,420 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (1.241) milliseconds per 285,521 loops.
  • Total difference 24.81 milliseconds for 5,710,420 loops

The iteration variablity for Code 1 was (3.4782) milliseconds and Code 2 was (0.9352) 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']);
