Result: DiscardedThe test labeled "Casting" was the faster by 0.0414 seconds, (3.667% faster)
The Casting test took 1.0877 seconds.
The is_float test took 1.1291 seconds.
Each test case ran 20 random code order iterations consisting of 286,202 loops for a total of 5,724,040 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (2.070) milliseconds per 286,202 loops.
- Total difference 41.40 milliseconds for 5,724,040 loops
The iteration variablity for Code 1 was (5.0327) milliseconds and Code 2 was (4.3745) 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'];
