Adminer Overview
Adminer is a free, open-source database management tool that ships as a single self-contained PHP file, created by Jakub Vrana. You place one small.php file on a web server and open it in a browser to administer your databases — there is nothing to install and no separate runtime beyond PHP itself. Despite its tiny footprint, it supports many database systems, including MySQL and MariaDB, PostgreSQL, SQLite, MS SQL, Oracle, and others through its driver system. From a clean web interface you can browse and edit tables and rows, run arbitrary SQL queries, manage users and permissions, import and export data as SQL or CSV, and work with schemas, indexes, and foreign keys. It is widely used as a lighter, single-file alternative to phpMyAdmin. Because the entire tool is one file, it runs on any machine with PHP and operates entirely on your own server, needing no external connection once the file has been downloaded.
