phpMyAdmin is a free software tool written in PHP, intended to handle the administration of MySQL over the Web.
phpMyAdmin supports a wide range of operations on MySQL and MariaDB. Frequently used operations (managing databases, tables, columns, relations, indexes, users, permissions, etc) can be performed via the user interface, while the user still has the ability to directly execute any SQL statement.
phpMyAdmin is a long time maintained project with a stable and flexible code base.
The phpMyAdmin project is a member of Sofware Freedom Conservancy. SFC is a not-for-profit organization that helps promote, improve, develop, and defend Free, Libre, and Open Source Software (FLOSS) projects.
