Config.php

A config.php file serves as a central repository for configuration settings, allowing developers to manage and modify application settings in a single location. This approach offers several benefits:

// Define variables $api_key = 'myapikey'; $api_secret = 'myapisecret'; config.php

To eliminate this risk, modern development pipelines rely on using files like .env . The Modern Approach: A config

// Database settings $db_host = 'localhost'; $db_name = 'mydatabase'; $db_username = 'myuser'; $db_password = 'mypassword'; $db_port = 3306; $api_secret = 'myapisecret'

// Database connection settings define('DB_HOST', 'localhost'); define('DB_USERNAME', 'myuser'); define('DB_PASSWORD', 'mypassword'); define('DB_NAME', 'mydatabase');

<?php // Configuration settings $config = array( 'database' => array( 'host' => 'localhost', 'username' => 'your_username', 'password' => 'your_password', 'name' => 'your_database' ), 'site' => array( 'title' => 'Your Site Title', 'email' => 'your_email@example.com' ) );
