Result: DiscardedThe test labeled "while (list)" was the faster by 0.0116 seconds, (2.023% faster)
The while (list) test took 0.5629 seconds.
The foreach test took 0.5745 seconds.
Each test case ran 20 random code order iterations consisting of 147,712 loops for a total of 2,954,240 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.581) milliseconds per 147,712 loops.
- Total difference 11.62 milliseconds for 2,954,240 loops
The iteration variablity for Code 1 was (3.2007) milliseconds and Code 2 was (2.4218) 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;
