Result: DiscardedThe test labeled "add operator" was the faster by 0.0939 seconds, (8.163% faster)
The add operator test took 1.0563 seconds.
The array_merge() test took 1.1502 seconds.
Each test case ran 20 random code order iterations consisting of 247,342 loops for a total of 4,946,840 runs.
- Line execution difference (0.000019) milliseconds.
- Avg difference (4.695) milliseconds per 247,342 loops.
- Total difference 93.90 milliseconds for 4,946,840 loops
The iteration variablity for Code 1 was (10.4059) milliseconds and Code 2 was (7.8555) 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'];
