SimplePie_Item::get_id
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 and title. If either of those are not supplied, creates a hash based on the full feed data.
Signature
public function get_id([boolean
$hash = false] )
Parameters
$hash
— boolean- Should we force using a hash instead of the supplied ID?
Returns
- string
