$user_id = 123; $url = "https://www.example.com/user/{$user_id}";
$search_query = $_GET['search']; $url = "https://www.example.com/search?q={$search_query}";In this example, the search query parameter is passed through the URL using a query string. Package libraries that might be useful for PHP URL generation include Symfony/Routing, GuzzleHttp, and Aura.Router. These libraries provide additional functionality and flexibility for handling URL routing and generation in PHP applications.
