Line execution difference (0.000028) milliseconds.
Avg difference (3.570) milliseconds per 126,439 loops.
Total difference 71.41 milliseconds for 2,528,780 loops

The iteration variablity for Code 1 was (7.0258) milliseconds and Code 2 was (8.9157) 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']++;
