Result: DiscardedThe test labeled "while (list)" was the faster by 0.0197 seconds, (1.545% faster)
The while (list) test took 1.253 seconds.
The foreach test took 1.2727 seconds.
Each test case ran 20 random code order iterations consisting of 283,207 loops for a total of 5,664,140 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.983) milliseconds per 283,207 loops.
- Total difference 19.67 milliseconds for 5,664,140 loops
The iteration variablity for Code 1 was (11.0180) milliseconds and Code 2 was (8.7685) 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;
