Result: DiscardedThe test labeled "Casting" was the faster by 0.0081 seconds, (1.324% faster)
The Casting test took 0.6009 seconds.
The is_float test took 0.609 seconds.
Each test case ran 20 random code order iterations consisting of 140,583 loops for a total of 2,811,660 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.403) milliseconds per 140,583 loops.
- Total difference 8.06 milliseconds for 2,811,660 loops
The iteration variablity for Code 1 was (6.3369) milliseconds and Code 2 was (4.9694) 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'];
