Is there anyway to delete field collections programmatically in Drupal 8? I have created a field collections and attached it to the user entity in the following method.

$user_id = \Drupal::currentUser()->getAccount()->id();
    $user = User::load($user_id);
    
    $fc = FieldCollectionItem::create(array(
          "field_name" => "field_hobbies",
    ));
    
    $fc->set('field_hobby_name', 'Watch TV');
    $fc->setHostEntity($user);

It works fine and the field collection created successfully. Now, I want to delete this field collection. That means, I want to delete the hobby from the user. Is there any way for doing this?

Thanks

Here is the answer:

$user = User::load($user_id);
$storage = \Drupal::entityTypeManager()->getStorage('field_collection_item');
$fc_items = [];

foreach ($user->get('field_hobbies') as $item) {
$fc_items[] = $item->value;
}

if (!empty($fc_items)) {
$items = $storage->loadMultiple($fc_items);
$storage->delete(items);
$user->set('field_hobbies', array());
}

$user->save();
