What is the importance of including the db.php file when working with databases in PHP?

Including the db.php file when working with databases in PHP is important because it typically contains the database connection code, which establishes a connection to the database server. This file often includes functions or classes that help in executing queries, fetching data, and handling errors related to the database operations. By including the db.php file in your PHP scripts, you can ensure that your database operations are centralized and reusable across multiple scripts. 

<?php
include 'db.php';
