Result: Discarded

The test labeled "clean code" was the faster by 0.0155 seconds, (1.938% faster)

clean code 100%
notices 98.062%

The clean code test took 0.7834 seconds.
The notices test took 0.7989 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 221,862 loops for a total of 4,437,240 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.774) milliseconds per 221,862 loops.
  • Total difference 15.48 milliseconds for 4,437,240 loops

The iteration variablity for Code 1 was (1.4542) milliseconds and Code 2 was (0.3827) 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']++;
