Result: DiscardedThe test labeled "add operator" was the faster by 0.0634 seconds, (4.839% faster)
The add operator test took 1.2458 seconds.
The array_merge() test took 1.3091 seconds.
Each test case ran 20 random code order iterations consisting of 289,212 loops for a total of 5,784,240 runs.
- Line execution difference (0.000011) milliseconds.
- Avg difference (3.168) milliseconds per 289,212 loops.
- Total difference 63.35 milliseconds for 5,784,240 loops
The iteration variablity for Code 1 was (11.1110) milliseconds and Code 2 was (7.6061) 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'];
