Result: Discarded
The test labeled "constants" was the faster by 0.0777 seconds, (7.374% faster)
The constants test took 0.9755 seconds.
The variables test took 1.0532 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 243,289 loops for a total of 4,865,780 runs.
- Line execution difference (0.000016) milliseconds.
- Avg difference (3.883) milliseconds per 243,289 loops.
- Total difference 77.67 milliseconds for 4,865,780 loops
The iteration variablity for Code 1 was (5.0158) milliseconds and Code 2 was (9.7030) 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']++;
