Result: DiscardedThe test labeled "add operator" was the faster by 0.0017 seconds, (0.233% faster)
The add operator test took 0.7198 seconds.
The array_merge() test took 0.7215 seconds.
Each test case ran 20 random code order iterations consisting of 127,515 loops for a total of 2,550,300 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.084) milliseconds per 127,515 loops.
- Total difference 1.68 milliseconds for 2,550,300 loops
The iteration variablity for Code 1 was (8.6020) milliseconds and Code 2 was (7.9385) 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, "add operator", was:
$array = $GLOBALS['dummy1'] + $GLOBALS['dummy2'] + $GLOBALS['dummy3'];
