Result: DiscardedThe test labeled "is_float" was the faster by 0.0039 seconds, (0.553% faster)
The is_float test took 0.7 seconds.
The Casting test took 0.7039 seconds.
Each test case ran 20 random code order iterations consisting of 186,953 loops for a total of 3,739,060 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.195) milliseconds per 186,953 loops.
- Total difference 3.89 milliseconds for 3,739,060 loops
The iteration variablity for Code 1 was (1.2429) milliseconds and Code 2 was (0.8089) 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'];
