Historical ResultsBased on (3) saved test runs, The test labeled "for" was (on average) the faster by 0.0034 seconds, (0.502% faster)
The for test took 0.6746 seconds.
The foreach test took 0.678 seconds.
Each test case ran 20 random code order iterations consisting of 177,550 loops for a total of 3,551,007 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.000) milliseconds per 177,550 loops.
- Total difference 3.40 milliseconds for 3,551,007 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, "foreach", was:
foreach ($GLOBALS['dummy'] as $v) $v + 1;
The second test, "for", was:
for ($k = 0, $n = count($GLOBALS['dummy']); $k < $n; $k++) $GLOBALS['dummy'][$k] + 1;
