Result: DiscardedThe test labeled "foreach" was the faster by 0.018 seconds, (1.618% faster)
The foreach test took 1.0935 seconds.
The while (list) test took 1.1115 seconds.
Each test case ran 20 random code order iterations consisting of 267,068 loops for a total of 5,341,360 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.899) milliseconds per 267,068 loops.
- Total difference 17.98 milliseconds for 5,341,360 loops
The iteration variablity for Code 1 was (3.1242) milliseconds and Code 2 was (2.8628) 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;
