Result: DiscardedThe test labeled "@define()" was the faster by 0.0655 seconds, (5.496% faster)
The @define() test took 1.1262 seconds.
The !defined() test took 1.1917 seconds.
Each test case ran 20 random code order iterations consisting of 271,432 loops for a total of 5,428,640 runs.
- Line execution difference (0.000012) milliseconds.
- Avg difference (3.275) milliseconds per 271,432 loops.
- Total difference 65.50 milliseconds for 5,428,640 loops
The iteration variablity for Code 1 was (5.9326) milliseconds and Code 2 was (7.7550) 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']);
