Based on (2) saved test runs, The test labeled "rawurlencode()" was (on average) the faster by 0.0171 seconds, (1.869% faster)

rawurlencode() 100%
urlencode() 98.131%

The rawurlencode() test took 0.8951 seconds.
The urlencode() test took 0.9121 seconds.


Each test case ran 20 random code order iterations consisting of 212,427 loops for a total of 4,248,530 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.000) milliseconds per 212,427 loops.
  • Total difference 17.05 milliseconds for 4,248,530 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, "urlencode()", was:

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

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

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