I've googled a bit but can't find a decent PHP tool that will let me upload an exported MYSQL DB file to a MYSQL server.
If you have remote mysql port access to the server, then just do on your local box with the dump file:
mysql < dumpfile -h remote.host.com -u remoteuser -p remotedbname
Then Bob's your uncle (whatever that means).
