Result: Discarded
The test labeled "variables" was the faster by 0.0165 seconds, (3.662% faster)
The variables test took 0.4344 seconds.
The constants test took 0.4509 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 115,944 loops for a total of 2,318,880 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (0.826) milliseconds per 115,944 loops.
- Total difference 16.51 milliseconds for 2,318,880 loops
The iteration variablity for Code 1 was (2.7040) milliseconds and Code 2 was (1.3142) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "constants", was:
define('CONSTANT' . $GLOBALS['i'], $GLOBALS['x'] . $GLOBALS['y'] . $GLOBALS['z']); $GLOBALS['i']++;
The second test, "variables", was:
$GLOBALS['CONSTANT' . $GLOBALS['i']] = $GLOBALS['x'] . $GLOBALS['y'] . $GLOBALS['z']; $GLOBALS['i']++;
