You can then create a dummy config.php inside the public folder that securely references the real one:

Without a configuration file, managing a website is a nightmare. Imagine you move your site to a new web host. Your database password will change. If you have a hundred different web pages, you would have to open every single file and update the password.

Common in WordPress ( wp-config.php ), this method makes variables immutable throughout the script execution. config.php

A file is a cornerstone of many PHP-based web applications, acting as a central hub for sensitive settings like database credentials, API keys, and site-wide constants. By consolidating these values into one file, developers can easily manage configurations across different environments (e.g., local development vs. production) without modifying the core application code. 1. Purpose and Role

$dotenv = Dotenv\Dotenv::createImmutable(__DIR__); $dotenv->load(); define('DB_HOST', $_ENV['DB_HOST']); define('DB_NAME', $_ENV['DB_NAME']); Use code with caution. 2. Local vs. Production Overrides

Because it handles sensitive credentials and database handshakes, managing your config.php file correctly is critical for both application performance and security. What is config.php? Method A: Using PHP Constants (Recommended for Global

At its core, config.php serves as the central nervous system for an application’s environment. It is the file that answers the most fundamental questions a script needs to run: Which database do I connect to? What is the secret key for user sessions? Is the system in development, testing, or production mode? By centralizing these disparate settings into a single location, the configuration file transforms a rigid script into a portable, adaptable application. Without it, sensitive credentials would be hard-coded across dozens of files, turning a simple server migration or password rotation into a harrowing scavenger hunt.
