The test labeled "is_float" was the faster by 0.0268 seconds, (3.273% faster)

is_float 100%
Casting 96.727%

The is_float test took 0.7913 seconds.
The Casting test took 0.818 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 204,003 loops for a total of 4,080,060 runs.

  • Line execution difference (0.000007) milliseconds.
  • Avg difference (1.339) milliseconds per 204,003 loops.
  • Total difference 26.78 milliseconds for 4,080,060 loops

The iteration variablity for Code 1 was (2.0361) milliseconds and Code 2 was (2.9884) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "is_float", was:

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

The second test, "Casting", was:

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