Result: DiscardedThe test labeled "while (list)" was the faster by 0.0216 seconds, (3.265% faster)
The while (list) test took 0.6411 seconds.
The foreach test took 0.6628 seconds.
Each test case ran 20 random code order iterations consisting of 129,144 loops for a total of 2,582,880 runs.
- Line execution difference (0.000008) milliseconds.
- Avg difference (1.082) milliseconds per 129,144 loops.
- Total difference 21.64 milliseconds for 2,582,880 loops
The iteration variablity for Code 1 was (6.6379) milliseconds and Code 2 was (7.9004) 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;
