Result: DiscardedThe test labeled "is_float" was the faster by 0.0198 seconds, (3.764% faster)
The is_float test took 0.5056 seconds.
The Casting test took 0.5253 seconds.
Each test case ran 20 random code order iterations consisting of 145,711 loops for a total of 2,914,220 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (0.989) milliseconds per 145,711 loops.
- Total difference 19.77 milliseconds for 2,914,220 loops
The iteration variablity for Code 1 was (0.2985) milliseconds and Code 2 was (0.5487) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "is_float", was:
$a = is_string($GLOBALS['test']);
The second test, "Casting", was:
$a = (string) $GLOBALS['test'] === $GLOBALS['test'];
