The Casting test took 1.3882 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 288,714 loops for a total of 5,774,280 runs.
- Line execution difference (0.000029) milliseconds.
- Avg difference (8.446) milliseconds per 288,714 loops.
- Total difference 168.91 milliseconds for 5,774,280 loops
The iteration variablity for Code 1 was (7.0253) milliseconds and Code 2 was (8.2827) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "is_int", was:
$a = is_int($GLOBALS['test']);
The second test, "Casting", was:
$a = (int) $GLOBALS['test'] === $GLOBALS['test'];
