The Casting test took 1.3402 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 283,494 loops for a total of 5,669,880 runs.
- Line execution difference (0.000025) milliseconds.
- Avg difference (7.145) milliseconds per 283,494 loops.
- Total difference 142.90 milliseconds for 5,669,880 loops
The iteration variablity for Code 1 was (10.4220) milliseconds and Code 2 was (16.1609) 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'];
