djith,
I know where you can find phpadmin in CPanel. If your web hosting service has CPanel, click on the icon for MYSQL databases, scroll to the very bottom of the page and in tiny letters there will be a hotlink that says "phpadmin".
But BEFORE you go mucking about in phpadmin, go to the Backup icon in CPanel and backup every one of your databases to your computer so that if something goes wrong you can easily restore the previous database.
