Historical ResultsBased on (3) saved test runs, The test labeled "array_merge()" was (on average) the faster by 0.0125 seconds, (1.589% faster)
The array_merge() test took 0.7753 seconds.
The add operator test took 0.7878 seconds.
Each test case ran 20 random code order iterations consisting of 210,458 loops for a total of 4,209,167 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 210,458 loops.
- Total difference 12.52 milliseconds for 4,209,167 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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'];
