Result: Discarded
The test labeled "@define()" was the faster by 0.0321 seconds, (3.689% faster)
The @define() test took 0.8372 seconds.
The !defined() test took 0.8693 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 214,597 loops for a total of 4,291,940 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (1.604) milliseconds per 214,597 loops.
- Total difference 32.07 milliseconds for 4,291,940 loops
The iteration variablity for Code 1 was (1.2533) milliseconds and Code 2 was (2.4645) 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']);
