urlencode() 100%
base64_encode() 96.448%

The urlencode() test took 0.8614 seconds.
The base64_encode() test took 0.8931 seconds.


Each test case ran 20 random code order iterations consisting of 203,841 loops for a total of 4,076,810 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (0.000) milliseconds per 203,841 loops.
  • Total difference 31.72 milliseconds for 4,076,810 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']);
