SimplePie_Item::get_id() │ public │ WP 2

Get the unique identifier for the item

This is usually used when writing code to check for new items in a feed.

Uses <atom:id>, <guid>, <dc:identifier> or the about attribute for RDF. If none of these are supplied (or $hash is true), creates an MD5 hash based on the permalink, title and content.
