Historical ResultsBased on (1) saved test runs, The test labeled "constants" was (on average) the faster by 0.0092 seconds, (1.404% faster)
The constants test took 0.6491 seconds.
The variables test took 0.6583 seconds.
Each test case ran 20 random code order iterations consisting of 141,056 loops for a total of 2,821,120 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 141,056 loops.
- Total difference 9.24 milliseconds for 2,821,120 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) milliseconds. The lower and the closer together there values are the more accurate the results are.
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']++;
