Result: DiscardedThe test labeled "defined()" was the faster by 0.0063 seconds, (1.102% faster)
The defined() test took 0.5668 seconds.
The isset() test took 0.5731 seconds.
Each test case ran 20 random code order iterations consisting of 141,186 loops for a total of 2,823,720 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.316) milliseconds per 141,186 loops.
- Total difference 6.32 milliseconds for 2,823,720 loops
The iteration variablity for Code 1 was (3.6589) milliseconds and Code 2 was (4.4129) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "defined()", was:
$GLOBALS['test'] = defined('CONSTANT');
The second test, "isset()", was:
$GLOBALS['test'] = isset($GLOBALS['CONSTANT']);
