phpMyAdmin is a feature-rich tool developed in PHP, which shall give you full control of a MySQL database. You could do practically everything - create fields, rows and tables, delete them or change their content, export or import a whole database or just a particular part of it, and execute MySQL commands. The tool is vital when you would like to switch web hosting providers, as you may very easily generate a full backup of a database in several formats (SQL, CSV, XML). You will end up with one file containing the whole content of the database, so you can easily download it from the present provider, upload it to the web server of the new one and import it using the same tool on their end. Your internet site will look exactly the same, simply because all script apps store their content in a database. With phpMyAdmin you can also quickly search and replace content material of your choice across the entire internet site - a word, a phrase or a link, for instance.
