Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 133,438 loops for a total of 2,668,760 runs.

  • Line execution difference (0.000012) milliseconds.
  • Avg difference (1.571) milliseconds per 133,438 loops.
  • Total difference 31.42 milliseconds for 2,668,760 loops

The iteration variablity for Code 1 was (5.3686) milliseconds and Code 2 was (5.9472) 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']++;
