File: multiple_upload_example.php
Role: Example script
Content type: text/plain
Description: Example and class extension
Class: Easy PHP Upload
Validate and manage files upload via Web forms
Author: By
Last change: In this version it's possible to use the rename function (timestamp) inside the multiple upload extension. In the same extension the filenames are validate too. I fixed small bug inside regex patter. Check the modified method upload_multi_files() and new variables.
