Historical ResultsBased on (6) saved test runs, The test labeled "in_array()" was (on average) the faster by 0.0134 seconds, (1.399% faster)
The in_array() test took 0.9456 seconds.
The key test took 0.959 seconds.
Each test case ran 20 random code order iterations consisting of 246,621 loops for a total of 4,932,420 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 246,621 loops.
- Total difference 13.41 milliseconds for 4,932,420 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, "in_array()", was:
for ($i = 0; $i < 10; $i++) $GLOBALS['dummy2'] = in_array($i * 20, $GLOBALS['dummy']);
The second test, "key", was:
for ($i = 0; $i < 10; $i++) $GLOBALS['dummy2'] = isset($GLOBALS['dummy'][$i * 20]);
