Historical ResultsBased on (1) saved test runs, The test labeled "constants" was (on average) the faster by 0.0145 seconds, (3.208% faster)
The constants test took 0.4366 seconds.
The variables test took 0.451 seconds.
Each test case ran 20 random code order iterations consisting of 104,271 loops for a total of 2,085,420 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (0.000) milliseconds per 104,271 loops.
- Total difference 14.47 milliseconds for 2,085,420 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:
$GLOBALS['test'] = CONSTANT + 1;
The second test, "variables", was:
$GLOBALS['test'] = $GLOBALS['CONSTANT'] + 1;
