Result: Discarded
The test labeled "notices" was the faster by 0.0253 seconds, (2.452% faster)
The notices test took 1.0078 seconds.
The clean code test took 1.0331 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 271,827 loops for a total of 5,436,540 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (1.267) milliseconds per 271,827 loops.
- Total difference 25.34 milliseconds for 5,436,540 loops
The iteration variablity for Code 1 was (3.5104) milliseconds and Code 2 was (4.1843) 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']++;
