// Define database connection settings $db_connection = array( 'host' => DB_HOST, 'username' => DB_USERNAME, 'password' => DB_PASSWORD, 'database' => DB_NAME );

Here is an example of a basic config.php file:

config.php is a PHP configuration file that contains settings and parameters for a web application. It is a script that defines various constants, variables, and functions that are used throughout the application to connect to databases, set up paths, and configure other essential components. The primary purpose of config.php is to provide a centralized location for storing and managing configuration data, making it easier to maintain and update the application.

// Define variables $api_key = 'myapikey'; $api_secret = 'myapisecret';

// Define path settings $root_dir = '/path/to/root/dir'; $uploads_dir = '/path/to/uploads/dir';

<?php // Define constants define('DB_HOST', 'localhost'); define('DB_USERNAME', 'myuser'); define('DB_PASSWORD', 'mypassword'); define('DB_NAME', 'mydatabase');
