1. 8.9.x core/modules/field_ui/src/Form/FieldStorageAddForm.php \Drupal\field_ui\Form\FieldStorageAddForm::getExistingFieldLabels()

Gets the human-readable labels for the given field storage names.

Since not all field storages are required to have a field, we can only provide the field labels on a best-effort basis (e.g. the label of a field storage without any field attached to a bundle will be the field name).

Parameters

array $field_names: An array of field names.

Return value

array An array of field labels keyed by field name.
