Result: DiscardedThe test labeled "while (list)" was the faster by 0.0134 seconds, (2.413% faster)
The while (list) test took 0.5403 seconds.
The foreach test took 0.5537 seconds.
Each test case ran 20 random code order iterations consisting of 128,551 loops for a total of 2,571,020 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.668) milliseconds per 128,551 loops.
- Total difference 13.36 milliseconds for 2,571,020 loops
The iteration variablity for Code 1 was (3.5676) milliseconds and Code 2 was (2.8043) 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;
