Historical ResultsBased on (2) saved test runs, The test labeled "is_int" was (on average) the faster by 0.0138 seconds, (2.037% faster)
The is_int test took 0.6618 seconds.
The Casting test took 0.6755 seconds.
Each test case ran 20 random code order iterations consisting of 169,257 loops for a total of 3,385,130 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.000) milliseconds per 169,257 loops.
- Total difference 13.76 milliseconds for 3,385,130 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "is_int", was:
$a = is_int($GLOBALS['test']);
The second test, "Casting", was:
$a = (int) $GLOBALS['test'] === $GLOBALS['test'];
