Result: DiscardedThe test labeled "array_merge()" was the faster by 0.0268 seconds, (2.604% faster)
The array_merge() test took 1.0025 seconds.
The add operator test took 1.0294 seconds.
Each test case ran 20 random code order iterations consisting of 278,783 loops for a total of 5,575,660 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (1.340) milliseconds per 278,783 loops.
- Total difference 26.81 milliseconds for 5,575,660 loops
The iteration variablity for Code 1 was (2.7406) milliseconds and Code 2 was (3.1519) 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'];
