In almost all respects the documentation is very good and much appreciated.
Just a small suggestion that the manual entry for the array_unique function should be a little more clear that the elements of the array argument must be scalar. Otherwise the function returns only the first array element. Thank you, Alan McEwen Alan McEwen & Associates 416-949-5709 17 Catherine Street, St. Catharines, ON, L2R 5E4
