Result: DiscardedThe test labeled "foreach" was the faster by 0.0423 seconds, (4.672% faster)
The foreach test took 0.8635 seconds.
The while (list) test took 0.9058 seconds.
Each test case ran 20 random code order iterations consisting of 199,823 loops for a total of 3,996,460 runs.
- Line execution difference (0.000011) milliseconds.
- Avg difference (2.116) milliseconds per 199,823 loops.
- Total difference 42.32 milliseconds for 3,996,460 loops
The iteration variablity for Code 1 was (2.8298) milliseconds and Code 2 was (3.5086) 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;
