The test labeled "urlencode()" was the faster by 0.0227 seconds, (2.673% faster)

urlencode() 100%
rawurlencode() 97.327%

The urlencode() test took 0.8257 seconds.

Each test case ran 20 random code order iterations consisting of 223,935 loops for a total of 4,478,700 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (1.134) milliseconds per 223,935 loops.
  • Total difference 22.68 milliseconds for 4,478,700 loops

The iteration variablity for Code 1 was (0.6207) milliseconds and Code 2 was (0.8632) 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']);
