Historical ResultsBased on (2) saved test runs, The test labeled "is_int" was (on average) the faster by 0.0098 seconds, (1.502% faster)
The is_int test took 0.6459 seconds.
The Casting test took 0.6557 seconds.
Each test case ran 20 random code order iterations consisting of 183,735 loops for a total of 3,674,700 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 183,735 loops.
- Total difference 9.85 milliseconds for 3,674,700 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'];
