Result: DiscardedThe test labeled "@define()" was the faster by 0.07 seconds, (6.861% faster)
The @define() test took 0.9508 seconds.
The !defined() test took 1.0208 seconds.
Each test case ran 20 random code order iterations consisting of 236,099 loops for a total of 4,721,980 runs.
- Line execution difference (0.000015) milliseconds.
- Avg difference (3.502) milliseconds per 236,099 loops.
- Total difference 70.03 milliseconds for 4,721,980 loops
The iteration variablity for Code 1 was (6.4022) milliseconds and Code 2 was (8.6033) 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']);
