Historical ResultsBased on (3) saved test runs, The test labeled "add operator" was (on average) the faster by 0.0257 seconds, (3.631% faster)
The add operator test took 0.6831 seconds.
The array_merge() test took 0.7088 seconds.
Each test case ran 20 random code order iterations consisting of 153,110 loops for a total of 3,062,207 runs.
- Line execution difference (0.000008) milliseconds.
- Avg difference (0.000) milliseconds per 153,110 loops.
- Total difference 25.74 milliseconds for 3,062,207 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'];
