$conn = mysqli_connect("localhost", "username", "password", "database"); $query = "SELECT * FROM users WHERE lastname = 'Doe'"; $result = $conn->queryRaw($query);
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017"); $query = new MongoDB\Driver\Query([]); $cursor = $manager->queryRaw('mydatabase.mycollection', $query);This code creates a MongoDB manager, defines a query to retrieve all documents from a collection, and uses `queryRaw` to execute the query on the database. Overall, `queryRaw` is a method used across multiple PHP package libraries that involves executing a raw SQL query directly on the database. The specific library used in these examples varies based on the database being accessed (e.g. mysqli for MySQL, MongoDB\Driver for MongoDB), but the `queryRaw` method itself is a common approach to executing raw queries in PHP.
