The is_float test took 0.7055 seconds.
The Casting test took 0.7158 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 139,357 loops for a total of 2,787,140 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.514) milliseconds per 139,357 loops.
- Total difference 10.28 milliseconds for 2,787,140 loops
The iteration variablity for Code 1 was (6.3070) milliseconds and Code 2 was (5.3863) 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'];
