Result: Discarded
The test labeled "notices" was the faster by 0.0199 seconds, (2.573% faster)
The notices test took 0.754 seconds.
The clean code test took 0.7739 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 168,717 loops for a total of 3,374,340 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (0.996) milliseconds per 168,717 loops.
- Total difference 19.91 milliseconds for 3,374,340 loops
The iteration variablity for Code 1 was (1.8767) milliseconds and Code 2 was (3.2430) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "notices", was:
for ($i = 0; $i < 100; $i++) $GLOBALS[dummy]++;
The second test, "clean code", was:
for ($i = 0; $i < 100; $i++) $GLOBALS['dummy']++;
