Parameters

array $edit: An array of submitted form values.

int $uid: The user ID of the user account to cancel.

string $method: The account cancellation method to use.

  // When the 'user_cancel_delete' method is used, user_delete() is called,

  // for the user entity. Modules should use those hooks to respond to the
  // account deletion.
  if ($method != 'user_cancel_delete') {

    // Allow modules to add further sets to this batch.
    \Drupal::moduleHandler()
      ->invokeAll('user_cancel', [
      $edit,
      $account,
      $method,
    ]);
  }

  // Finish the batch and actually cancel the account.
  $batch = [

  batch_set($batch);

  // Batch processing is either handled via Form API or has to be invoked
