Historical ResultsBased on (7) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0078 seconds, (0.976% faster)
The foreach test took 0.7954 seconds.
The for test took 0.8032 seconds.
Each test case ran 20 random code order iterations consisting of 198,375 loops for a total of 3,967,497 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 198,375 loops.
- Total difference 7.84 milliseconds for 3,967,497 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;
