phpMyAdmin is a very popular web-based MySQL database management tool. A MySQL database management tool based on PHP and structured on the website host in a Web-Base manner. It can create and delete databases, create/delete/modify tables, delete/edit/add fields, execute SQL scripts, etc. phpMyAdmin can manage the entire MySQL server (requires superuser) or a single database. In order to achieve the latter, you will need to set up the MySQL user appropriately so that he can only read/write to allowed databases. That's until you read the relevant section in the MySQL manual.
