Test: (array) vs. array w/is_array
Does the (array) cast work better than the array() construct if you might already have an array?
Run this test again Return to test menuResult: Discarded
The test labeled "is_array() ? x : array(x)" was the faster by 0.0078 seconds, (1.087% faster)
The is_array() ? x : array(x) test took 0.7139 seconds.
The (array) test took 0.7218 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 183,157 loops for a total of 3,663,140 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.392) milliseconds per 183,157 loops.
- Total difference 7.84 milliseconds for 3,663,140 loops
The iteration variablity for Code 1 was (4.7273) milliseconds and Code 2 was (4.3226) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "(array)", was:
for ($j = 0; $j < 1000; $j++) $GLOBALS['dummy'] = (array) $j;
The second test, "is_array() ? x : array(x)", was:
for ($j = 0; $j < 1000; $j++) $GLOBALS['dummy'] = is_array($j) ? $j : array($j);
