Result: DiscardedThe test labeled "while (list)" was the faster by 0.0744 seconds, (5.647% faster)
The while (list) test took 1.243 seconds.
The foreach test took 1.3174 seconds.
Each test case ran 20 random code order iterations consisting of 273,913 loops for a total of 5,478,260 runs.
- Line execution difference (0.000014) milliseconds.
- Avg difference (3.719) milliseconds per 273,913 loops.
- Total difference 74.39 milliseconds for 5,478,260 loops
The iteration variablity for Code 1 was (10.1959) milliseconds and Code 2 was (13.0739) 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;
