How can potential errors during user creation and deletion be effectively handled in CakePHP controllers?

Potential errors during user creation and deletion in CakePHP controllers can be effectively handled by using try-catch blocks to catch any exceptions that may occur during these processes. By wrapping the user creation and deletion logic in try-catch blocks, we can gracefully handle any errors that may arise, such as database connection issues or validation failures. 

try {
    // User creation logic
    $user = $this->Users->newEntity($this->request->getData());
    if ($this->Users->save($user)) {
        // User successfully created
    } else {
        // Error saving user
    }
} catch (\Exception $e) {
    // Handle any errors that occurred during user creation
}

try {
    // User deletion logic
    $user = $this->Users->get($id);
    if ($this->Users->delete($user)) {
        // User successfully deleted
    } else {
        // Error deleting user
    }
} catch (\Exception $e) {
    // Handle any errors that occurred during user deletion
}
