phpMyAdmin is a free and open-source web-based tool that allows users to manage and interact with MySQL or MariaDB databases through a web interface. It is often used in WordPress for managing the WordPress database.
Since WordPress works on MySQL or MariaDB database only, phpMyAdmin is a popular database administering system among WordPress users.
In WordPress, the database stores all of the content, settings, and configurations for your website. phpMyAdmin allows you to manage your WordPress database directly, including creating and editing tables, running SQL queries, importing and exporting data, and optimizing the database.
phpMyAdmin is often accessed through the cPanel or other hosting control panels. It is important to be careful when using phpMyAdmin, as any changes made to the database can have a significant impact on your WordPress site. It is recommended to create a backup of your database before making any changes using phpMyAdmin.
