Based on (2) saved test runs, The test labeled "base64_encode()" was (on average) the faster by 0.0175 seconds, (2.903% faster)

base64_encode() 100%
urlencode() 97.097%

The base64_encode() test took 0.5845 seconds.
The urlencode() test took 0.602 seconds.


Each test case ran 20 random code order iterations consisting of 134,914 loops for a total of 2,698,280 runs.

  • Line execution difference (0.000006) milliseconds.
  • Avg difference (0.000) milliseconds per 134,914 loops.
  • Total difference 17.48 milliseconds for 2,698,280 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, "base64_encode()", was:

$GLOBALS['dummy2'] = base64_encode($GLOBALS['dummy']);
