Result: Discarded
The test labeled "clean code" was the faster by 0.0173 seconds, (3.205% faster)
The clean code test took 0.5225 seconds.
The notices test took 0.5398 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 133,110 loops for a total of 2,662,200 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (0.865) milliseconds per 133,110 loops.
- Total difference 17.30 milliseconds for 2,662,200 loops
The iteration variablity for Code 1 was (3.2797) milliseconds and Code 2 was (2.0738) 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']++;
