Result: DiscardedThe test labeled "for" was the faster by 0.0067 seconds, (1.106% faster)
The for test took 0.5972 seconds.
The array_merge() test took 0.6039 seconds.
Each test case ran 20 random code order iterations consisting of 162,806 loops for a total of 3,256,120 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.334) milliseconds per 162,806 loops.
- Total difference 6.68 milliseconds for 3,256,120 loops
The iteration variablity for Code 1 was (1.5633) milliseconds and Code 2 was (1.0451) 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];
