The test labeled "Casting" was the faster by 0.0169 seconds, (2.754% faster)

Casting 100%
is_int 97.246%

The Casting test took 0.5961 seconds.
The is_int test took 0.613 seconds.


Each test case ran 20 random code order iterations consisting of 157,621 loops for a total of 3,152,420 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.844) milliseconds per 157,621 loops.
  • Total difference 16.88 milliseconds for 3,152,420 loops

The iteration variablity for Code 1 was (3.2072) milliseconds and Code 2 was (1.8658) 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'];
