if (!isProduction) { error_reporting(E_ALL); ini_set('display_errors', 'on'); }
if (isProduction) { $connection = new PDO('mysql:host=production_host;dbname=mydatabase', 'username', 'password'); } else { $connection = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password'); }In this example, the database connection depends on whether the environment is a production environment or not. If it is, a different host and credentials will be used to connect to the database. The package library that might be used to implement this function might be Dotenv, which allows developers to set environment variables in a .env file and then access them in their PHP code.
