// Get the current environment instance $environment = \Symfony\Component\Dotenv\Environment::getInstance(); // Use the environment instance to get a value from an environment variable $databaseUrl = $environment->get('DATABASE_URL');
// Get the current environment instance $environment = \Symfony\Component\HttpFoundation\Request::createFromGlobals()->server; // Use the environment instance to get a value from the "HTTP_USER_AGENT" variable $userAgent = $environment->get('HTTP_USER_AGENT');This example shows how to get a specific instance of the environment, in this case, the environment associated with the current HTTP request. This can be useful when you need to extract information from the current request in your PHP code. In both examples, the package library being used is "Symfony". This library provides a number of useful PHP components for building web applications.
