Result: Discarded
The test labeled "@define()" was the faster by 0.018 seconds, (2.678% faster)
The @define() test took 0.6558 seconds.
The !defined() test took 0.6738 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 134,583 loops for a total of 2,691,660 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (0.902) milliseconds per 134,583 loops.
- Total difference 18.05 milliseconds for 2,691,660 loops
The iteration variablity for Code 1 was (2.1170) milliseconds and Code 2 was (2.9966) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "@define()", was:
@define('CONSTANT', $GLOBALS['dummy']);
The second test, "!defined()", was:
if (!defined('CONSTANT'))
define('CONSTANT', $GLOBALS['dummy']);
