Each test case ran 20 random code order iterations consisting of 279,294 loops for a total of 5,585,880 runs.

  • Line execution difference (0.000007) milliseconds.
  • Avg difference (2.023) milliseconds per 279,294 loops.
  • Total difference 40.46 milliseconds for 5,585,880 loops

The iteration variablity for Code 1 was (0.8257) milliseconds and Code 2 was (2.0592) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "file_exists()", was:


if (!file_exists('supplement/'))
