Result: Discarded

The test labeled "urlencode()" was the faster by 0.0197 seconds, (1.967% faster)

urlencode() 100%
rawurlencode() 98.033%

The urlencode() test took 0.9803 seconds.
The rawurlencode() test took 1 seconds.


Each test case ran 20 random code order iterations consisting of 263,295 loops for a total of 5,265,900 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.983) milliseconds per 263,295 loops.
  • Total difference 19.67 milliseconds for 5,265,900 loops

The iteration variablity for Code 1 was (4.0641) milliseconds and Code 2 was (5.4590) 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']);
