Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 281,355 loops for a total of 5,627,100 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (2.336) milliseconds per 281,355 loops.
  • Total difference 46.72 milliseconds for 5,627,100 loops

The iteration variablity for Code 1 was (7.7150) milliseconds and Code 2 was (7.0232) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "@ (shut up)", was:

@$GLOBALS['dummy']++;

The second test, "without @", was:

$GLOBALS['dummy']++;
