phpMyAdmin is a highly efficient PHP-based tool used to control MySQL databases through a web interface. You may use it to run MySQL commands, set up, modify and remove cells, rows and tables or manage users with different levels of access to the database in question. Every single one of these tasks can easily be performed from any device provided that you have a browser and access to the hosting account where the database is. With phpMyAdmin, you can also export or import an entire database, which is a very useful feature if you'd like to migrate a web site from one web hosting company to another. A number of different file formats are supported for the so-called dump file - CSV, SQL, XML and PDF, dependant upon what you want to do - move the content from one internet hosting account to another, preview an entire database in a spreadsheet app such as Microsoft Excel, etc.
