This document provides examples of how to connect to and query a Microsoft Access database from PHP using ODBC. It demonstrates connecting to Access and performing basic CRUD (create, read, update, delete) operations as well as displaying results of a SELECT query in an HTML table. Specific connection strings and SQL statements for inserting, deleting, updating and selecting data from an Access table are shown.
