This document discusses connecting a PHP application to a MySQL database. It shows how to connect to the database, execute SQL queries, and retrieve and display the results. Code examples are provided to connect to the database, run SELECT queries, fetch the results into arrays, and loop through the arrays to display the data. Functions are demonstrated to encapsulate the database connection and query execution code for reuse. Finally, examples show how to generate HTML tables and dropdown lists to display the database data.
