Run this test again Return to test menu

Result: Discarded

The test labeled "Casting" was the faster by 0.0134 seconds, (2.065% faster)

Casting 100%
is_int 97.935%

The Casting test took 0.6348 seconds.
The is_int test took 0.6482 seconds.


Each test case ran 20 random code order iterations consisting of 146,155 loops for a total of 2,923,100 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.669) milliseconds per 146,155 loops.
  • Total difference 13.39 milliseconds for 2,923,100 loops

The iteration variablity for Code 1 was (8.5518) milliseconds and Code 2 was (6.2493) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "is_int", was:

$a = is_int($GLOBALS['test']);

The second test, "Casting", was:

$a = (int) $GLOBALS['test'] === $GLOBALS['test'];
