class User { // properties and other methods... public function isUserAdmin() { if ($this->isAdmin) { return true; } else { return false; } } }This code snippet checks if the user has the isAdmin property set to true and returns true if so, otherwise it returns false. This function can be used in various parts of the application to check if a user is authorized to perform certain actions, such as accessing an admin dashboard or modifying user data. The package library that contains the User model and isUserAdmin method may vary depending on the application framework being used. For example, in the Laravel framework, these functions may be part of the Illuminate\Auth\Authenticatable trait.
