How are MySQL and PHP related?
MySQL is a database system that can be used for information storage. On the CIS server, a MySQL database is primarily used by advanced web developers to store information from web forms, like sign-ups, rosters, and bulletin boards / forums boards such as this one. PHP, on the other hand, is a scripting language. On the CIS server, it is typically used to process web form information. PHP can be used to take web form data and insert it into a MySQL database, or it can be used to e-mail the information to a specified e-mail address. PHP and MySQL work well together, but they are not dependent upon each other and other technologies can be used for web forms and scripting, too.
