Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 287,675 loops for a total of 5,753,500 runs.

Line execution difference (0.000004) milliseconds.
Avg difference (1.066) milliseconds per 287,675 loops.
Total difference 21.32 milliseconds for 5,753,500 loops

The iteration variablity for Code 1 was (6.6559) milliseconds and Code 2 was (3.3354) 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']++;
