Result: Discarded
The test labeled "notices" was the faster by 0.0371 seconds, (7.041% faster)
The notices test took 0.4904 seconds.
The clean code test took 0.5275 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 138,425 loops for a total of 2,768,500 runs.
- Line execution difference (0.000013) milliseconds.
- Avg difference (1.857) milliseconds per 138,425 loops.
- Total difference 37.15 milliseconds for 2,768,500 loops
The iteration variablity for Code 1 was (0.6304) milliseconds and Code 2 was (2.6155) 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']++;
