// include the database library require_once('db_library.php'); // get the user details from a form submission $username = $_POST['username']; $password = $_POST['password']; $email = $_POST['email']; // use the add_user function to insert the new user into the database add_user($username, $password, $email);
// include the user library require_once('user_library.php'); // get the user details from a form submission $username = $_POST['username']; $password = $_POST['password']; $email = $_POST['email']; // create a new instance of the User class $user = new User(); // use the add_user method to insert the new user into the system $user->add_user($username, $password, $email);In this example, the add_user function is part of a user library that is included using the require_once keyword. The user details are retrieved from a form submission and passed as parameters to the add_user method of an instance of the User class. The User class is assumed to be part of a larger package library. Package/library: The package library in these examples is not specified, as it could be any custom or third-party library that provides the add_user function. However, the function is typically used in PHP applications that involve user registration or login, and may be part of a larger framework or CMS system.
