entity_extract_ids in ViewsPHP field

I need get host entity id from field_collection_item. I've tried:

$current_item = entity_load('field_collection_item', array($row->item_id));
$entity_type = entity_get_info('field_collection_item');
list($host_id, $host_vid, $host_bundle) = entity_extract_ids($entity_type, $current_item);

print $host_id;

But "Warning: Illegal offset type in isset or empty in entity_get_info() (line 7367)".

How to get host entity id from field_collection? Help, please :-)
