What are the potential drawbacks of manually searching for constant definitions in the source code?

Manually searching for constant definitions in the source code can be time-consuming and prone to human error. To streamline this process, you can create a dedicated file to store all constant definitions and include it in your project. This centralizes all constants in one place, making it easier to manage and reference them throughout your codebase. 

// constants.php
define('DB_HOST', 'localhost');
define('DB_USER', 'root');
define('DB_PASS', 'password');
define('DB_NAME', 'database_name');

// index.php
include 'constants.php';

// Now you can use the constants throughout your codebase
echo DB_HOST;
echo DB_USER;
echo DB_PASS;
echo DB_NAME;
