Result: DiscardedThe test labeled "foreach" was the faster by 0.049 seconds, (8.446% faster)
The foreach test took 0.5314 seconds.
The while (list) test took 0.5804 seconds.
Each test case ran 20 random code order iterations consisting of 147,142 loops for a total of 2,942,840 runs.
- Line execution difference (0.000017) milliseconds.
- Avg difference (2.451) milliseconds per 147,142 loops.
- Total difference 49.03 milliseconds for 2,942,840 loops
The iteration variablity for Code 1 was (1.9404) milliseconds and Code 2 was (4.8034) 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;
