Result: DiscardedThe test labeled "foreach" was the faster by 0.0234 seconds, (3.400% faster)
The foreach test took 0.6637 seconds.
The while (list) test took 0.6871 seconds.
Each test case ran 20 random code order iterations consisting of 134,046 loops for a total of 2,680,920 runs.
- Line execution difference (0.000009) milliseconds.
- Avg difference (1.168) milliseconds per 134,046 loops.
- Total difference 23.36 milliseconds for 2,680,920 loops
The iteration variablity for Code 1 was (10.8674) milliseconds and Code 2 was (10.6711) 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;
