Result: DiscardedThe test labeled "@define()" was the faster by 0.0226 seconds, (4.837% faster)
The @define() test took 0.4453 seconds.
The !defined() test took 0.468 seconds.
Each test case ran 20 random code order iterations consisting of 128,227 loops for a total of 2,564,540 runs.
- Line execution difference (0.000009) milliseconds.
- Avg difference (1.132) milliseconds per 128,227 loops.
- Total difference 22.64 milliseconds for 2,564,540 loops
The iteration variablity for Code 1 was (0.4725) milliseconds and Code 2 was (1.8187) 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']);
