Result: Discarded
The test labeled "@define()" was the faster by 0.0107 seconds, (1.466% faster)
The @define() test took 0.7225 seconds.
The !defined() test took 0.7332 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 149,396 loops for a total of 2,987,920 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.537) milliseconds per 149,396 loops.
- Total difference 10.75 milliseconds for 2,987,920 loops
The iteration variablity for Code 1 was (7.9849) milliseconds and Code 2 was (4.8929) 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']);
