Based on (3) saved test runs, The test labeled "notices" was (on average) the faster by 0.0017 seconds, (0.336% faster)

notices 100%
clean code 99.664%

The notices test took 0.5107 seconds.
The clean code test took 0.5124 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 138,611 loops for a total of 2,772,227 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.000) milliseconds per 138,611 loops.
  • Total difference 1.72 milliseconds for 2,772,227 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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']++;
