phpMyAdmin is a powerful PHP-based tool used to control MySQL databases via a web interface. You can use it to run MySQL commands, create, edit and erase cells, rows and tables or manage users with separate levels of access to the database in question. Every one of these tasks may be done from any device given that you have a web browser and access to the website hosting account where the database is. With phpMyAdmin, you could also export or import a whole database, which is a very helpful feature if you would like to migrate a website from one web hosting provider to another. A variety of file formats are supported for the so-called dump file - CSV, SQL, XML and PDF, dependant upon what you would like to do - move the content from one web hosting account to another, preview an entire database in a spreadsheet app like Microsoft Excel, etc.
