The clean code test took 0.7834 seconds.
The notices test took 0.7989 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 221,862 loops for a total of 4,437,240 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.774) milliseconds per 221,862 loops.
- Total difference 15.48 milliseconds for 4,437,240 loops
The iteration variablity for Code 1 was (1.4542) milliseconds and Code 2 was (0.3827) 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']++;
