Historical ResultsBased on (3) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0162 seconds, (2.521% faster)
The foreach test took 0.627 seconds.
The while (list) test took 0.6432 seconds.
Each test case ran 20 random code order iterations consisting of 167,300 loops for a total of 3,346,007 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.000) milliseconds per 167,300 loops.
- Total difference 16.21 milliseconds for 3,346,007 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) $v + 1;
The second test, "while (list)", was:
reset($GLOBALS['dummy']); while (list(, $v) = each($GLOBALS['dummy'])) $v + 1;
