Result: Discarded

The test labeled "clean code" was the faster by 0.0173 seconds, (3.205% faster)

clean code 100%
notices 96.795%

The clean code test took 0.5225 seconds.
The notices test took 0.5398 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 133,110 loops for a total of 2,662,200 runs.

  • Line execution difference (0.000006) milliseconds.
  • Avg difference (0.865) milliseconds per 133,110 loops.
  • Total difference 17.30 milliseconds for 2,662,200 loops

The iteration variablity for Code 1 was (3.2797) milliseconds and Code 2 was (2.0738) 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']++;
