Closed 8 years ago.

i am trying to display a number from which is the amount of files in a folder in my directory within my website.

i have tried to do many methods of this which i have found on the net but still have no clue maybe its because i am unsure of the location of the directory

the location of the folder is

www/documents

and here is my code

<?php iterator_count(new DirectoryIterator('/documents/'));?>
