Sweet PHP backup / dump function for MySQL database

Right now, I'm using phpMyAdmin to periodically backup/dump a client MySQL database to a textfile (from which one can simply restore the database if it ever got corrupted). I'm also working on a super-simple CMS for the client to use themselves. I would like the client to also be able to easily "backup" his web site's MySQL database to a textfile and have that textfile emailed to whatever address he specifies. Sort of a two step approach: Enter email _________ < Backup and send database > (click) I imagine someone somewhere has written a very nice function for doing this, which might take a few parameters, such as database, destination email address, etc. The main thing is that the function include complete inserts, extended inserts, backquotes, etc. Anyone have a sweet function like this they wanna share, and in so doing make the world a better place? :-) ...Rene
