Result: Discarded

The test labeled "is_int" was the faster by 0.0679 seconds, (11.122% faster)

is_int 100%
Casting 88.878%

The is_int test took 0.5423 seconds.
The Casting test took 0.6102 seconds.


Each test case ran 20 random code order iterations consisting of 146,359 loops for a total of 2,927,180 runs.

  • Line execution difference (0.000023) milliseconds.
  • Avg difference (3.393) milliseconds per 146,359 loops.
  • Total difference 67.87 milliseconds for 2,927,180 loops

The iteration variablity for Code 1 was (1.7723) milliseconds and Code 2 was (6.4754) 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'];
