Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 279,900 loops for a total of 5,598,000 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (1.327) milliseconds per 279,900 loops.
  • Total difference 26.54 milliseconds for 5,598,000 loops

The iteration variablity for Code 1 was (1.1873) milliseconds and Code 2 was (1.1270) 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']++;
