Anyone have access to a Facebook Viral Force Share php script for Messenger?

Hi there,

I'm looking for a Facebook viral force share php script that is working for today and would be integrated into Messenger as a "share with 10 friends to unlock this offer" kind of thing.

everything I'm seeing online is either outdated or is in the update process. Does someone have a working script for this that they'd be willing to discuss/share? Also willing to purchase.

Thanks.
