Historical ResultsBased on (3) saved test runs, The test labeled "foreach" was (on average) the faster by 0.0164 seconds, (2.271% faster)
The foreach test took 0.7072 seconds.
The for test took 0.7236 seconds.
Each test case ran 20 random code order iterations consisting of 190,750 loops for a total of 3,815,000 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.000) milliseconds per 190,750 loops.
- Total difference 16.44 milliseconds for 3,815,000 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;
