phpMyAdmin is a powerful PHP-based software tool employed to handle MySQL databases via a web interface. You could use it to run MySQL commands, set up, modify and erase cells, rows and tables or control users with different levels of access to the database in question. All these tasks could be done from any device as long as you have a browser and access to the web hosting account in which the database is. With phpMyAdmin, you can also export or import an entire database, which is a very beneficial feature if you want to migrate a website from one web hosting provider to another. Many different file formats are supported for the so-called dump file - CSV, SQL, XML and PDF, dependant upon what you'd like to do - move the content from one web hosting account to another, preview a whole database in a spreadsheet app like Microsoft Excel, etc.
