Result: DiscardedThe test labeled "while (list)" was the faster by 0.0154 seconds, (1.390% faster)
The while (list) test took 1.0908 seconds.
The foreach test took 1.1062 seconds.
Each test case ran 20 random code order iterations consisting of 278,645 loops for a total of 5,572,900 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.769) milliseconds per 278,645 loops.
- Total difference 15.38 milliseconds for 5,572,900 loops
The iteration variablity for Code 1 was (2.7213) milliseconds and Code 2 was (1.7774) 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;
