Historical Results

Based on (2) saved test runs, The test labeled "clean code" was (on average) the faster by 0.0141 seconds, (1.299% faster)

clean code 100%
notices 98.701%

The clean code test took 1.0684 seconds.
The notices test took 1.0824 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 275,691 loops for a total of 5,513,820 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.000) milliseconds per 275,691 loops.
  • Total difference 14.06 milliseconds for 5,513,820 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']++;
