Result: DiscardedThe test labeled "for" was the faster by 0.0753 seconds, (8.965% faster)
The for test took 0.7647 seconds.
The array_merge() test took 0.84 seconds.
Each test case ran 20 random code order iterations consisting of 156,943 loops for a total of 3,138,860 runs.
- Line execution difference (0.000024) milliseconds.
- Avg difference (3.765) milliseconds per 156,943 loops.
- Total difference 75.30 milliseconds for 3,138,860 loops
The iteration variablity for Code 1 was (6.7832) milliseconds and Code 2 was (6.3901) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "array_merge()", was:
$array = array_merge($GLOBALS['dummy1'], $GLOBALS['dummy2'], $GLOBALS['dummy3']);
The second test, "for", was:
$array = $GLOBALS['dummy1']; for ($i = 0, $n = count($GLOBALS['dummy2']); $i < $n; $i++) $array = $GLOBALS['dummy2'][$i]; for ($i = 0, $n = count($GLOBALS['dummy3']); $i < $n; $i++) $array = $GLOBALS['dummy3'][$i];
