Once you set up phpMyAdmin, whenever you log in, you’ll be able to pick the server you want to work with from a dropdown list. All the normal features of phpMyAdmin will be available, and the only difference you might note (compared to using phpMyAdmin with a local database) is a slight delay because of transmission times. You can perform all sorts of administrative tasks remotely, including database creation or modification, backups, and queries.
There’s plenty of documentation available for using phpMyAdmin online — just Google a bit – or get a copy of Mastering phpMyAdmin 2.8 for Effective MySQL Management from Packt Publishing.
Manipulating remote MySQL databases with phpMyAdmin is simple, and you don’t even have to install any software on other servers. phpMyAdmin provides an easy graphical interface that’s appropriate for most administrative tasks.
