Historical ResultsBased on (5) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0098 seconds, (1.000% faster)
The foreach test took 0.9745 seconds.
The for test took 0.9843 seconds.
Each test case ran 20 random code order iterations consisting of 253,523 loops for a total of 5,070,464 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 253,523 loops.
- Total difference 9.84 milliseconds for 5,070,464 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "foreach", was:
$range = range(0, 100); foreach ($range as $n) $GLOBALS['dummy'] = $n;
The second test, "for", was:
for ($n = 0; $n <= 100; $n++) $GLOBALS['dummy'] = $n;
