Use PHP to copy MySQL tables

Is there an easy way to create an HTML page that uses PHP to copy selected MySQL tables to backup copies on the same MySQL server? I want to create an administration page for my client to be able to "backup" their database whenever they see fit. But, I can't give them direct access to the MySQL server and don't want them backing up to their hard drive. I prefer to simply copy the tables to "backup" versions on the server so that if problems arise, I can log into the server and simply copy the "backups" to the originals. Thanx in advance. -- Robb Kerr Digital IGUANA Helping Digital Artists Achieve their Dreams http://www.digitaliguana.com http://www.cancerreallysucks.org
