Historical ResultsBased on (6) saved test runs, The test labeled "variables" was (on average) the faster by 0.0005 seconds, (0.050% faster)
The variables test took 0.9132 seconds.
The constants test took 0.9137 seconds.
Each test case ran 20 random code order iterations consisting of 201,682 loops for a total of 4,033,633 runs.
- Line execution difference (0.000000) milliseconds.
- Avg difference (0.000) milliseconds per 201,682 loops.
- Total difference 0.46 milliseconds for 4,033,633 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']++;
