Each test case ran 20 random code order iterations consisting of 134,637 loops for a total of 2,692,740 runs.

  • Line execution difference (0.000018) milliseconds.
  • Avg difference (2.490) milliseconds per 134,637 loops.
  • Total difference 49.79 milliseconds for 2,692,740 loops

The iteration variablity for Code 1 was (6.4552) milliseconds and Code 2 was (5.8371) 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/'))
