Result: Discarded

The test labeled "notices" was the faster by 0.0253 seconds, (2.452% faster)

notices 100%
clean code 97.548%

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']++;
