Result: DiscardedThe test labeled "@define()" was the faster by 0.0285 seconds, (2.897% faster)
The @define() test took 0.9549 seconds.
The !defined() test took 0.9834 seconds.
Each test case ran 20 random code order iterations consisting of 246,542 loops for a total of 4,930,840 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (1.424) milliseconds per 246,542 loops.
- Total difference 28.49 milliseconds for 4,930,840 loops
The iteration variablity for Code 1 was (2.6847) milliseconds and Code 2 was (2.8647) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "@define()", was:
The second test, "!defined()", was:
if (!defined('CONSTANT')) define('CONSTANT', $GLOBALS['dummy']);
