phpMyAdmin is a web-based tool available in cPanel that allows you to manage MySQL (and MariaDB) databases through an easy-to-use graphical interface. With phpMyAdmin, you can perform various tasks such as creating and editing databases, running SQL queries, importing and exporting data, managing tables, and setting user permissions, without needing to use command-line tools.
It’s a powerful feature for website administrators and developers who need to interact directly with their site's database.
