Note Submitter: www dot php dot net dot 2nd at mailfilter dot com dot ar ---- To the bemused poster: Of course you can't compare processing times between functions/no functions. I only wanted to see the difference between referenced and copied variables in different scenarios. Tests are only meant to compare between pairs (i.e., call a function with & and call the same function without &). I did 4 individual pairs of tests, so test 1 compares to test 2, test 3 compares to test 4, test 5 compares to test 6 and test 7 compares to test 8. The strlen() call was there only to make sure the value is actually accessed.
