Historical ResultsBased on (4) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0257 seconds, (2.225% faster)
The foreach test took 1.1301 seconds.
The for test took 1.1558 seconds.
Each test case ran 20 random code order iterations consisting of 244,634 loops for a total of 4,892,670 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.000) milliseconds per 244,634 loops.
- Total difference 25.72 milliseconds for 4,892,670 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;
