Result: DiscardedThe test labeled "@define()" was the faster by 0.025 seconds, (2.567% faster)
The @define() test took 0.9475 seconds.
The !defined() test took 0.9725 seconds.
Each test case ran 20 random code order iterations consisting of 249,178 loops for a total of 4,983,560 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (1.248) milliseconds per 249,178 loops.
- Total difference 24.96 milliseconds for 4,983,560 loops
The iteration variablity for Code 1 was (1.6458) milliseconds and Code 2 was (2.5856) 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']);
