Variables in PHP hold information, but only for the length of the program. You can fill in a form to get information, but you need to store it somewhere. You need a place to hold your data that is still there after the program ends. This section introduces you to what databases are and how to design a database. You learn how to create a MySQL database, how to set up the appropriate tables, and how to use the MySQL scripting language within PHP to create, update, query, and delete information.
