$username = $_POST['username']; $password = $_POST['password']; $query = "SELECT * FROM users WHERE username = " . DB::quote($username) . " AND password = " . DB::quote($password); // execute the query $result = DB::query($query);
$user_id = 42; $query = "DELETE FROM users WHERE id = " . DB::quote($user_id); // execute the query $result = DB::query($query);In this example, we use DB quote to escape and quote the user ID before using it in a SQL query to delete a user from the database. The PHP DB quote function is a part of the PHP PDO (PHP Data Objects) package library. It is specifically a part of the PDO database extension which provides a unified interface for accessing various database management systems.
