Historical Results

Based on (1) saved test runs, The test labeled "urlencode()" was (on average) the faster by 0.0264 seconds, (2.253% faster)

urlencode() 100%
rawurlencode() 97.747%

The urlencode() test took 1.1437 seconds.
The rawurlencode() test took 1.17 seconds.


Each test case ran 20 random code order iterations consisting of 287,675 loops for a total of 5,753,500 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.000) milliseconds per 287,675 loops.
  • Total difference 26.36 milliseconds for 5,753,500 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']);
