Communicating with another web site

[gascar]

Apologies if this is an old/dumb/misplaced question!

I want to check a user is a member of a group registered on a 3rd party site.

LIKE - if it was a bidsniper utility I wanted to create, user would give login details and item number to me, I'd use them at ebay to find the finishing time, log in, make the bid, return the result.


Is there a "name" for this sort of activity I can search on?
I assume this would be a PHP/SQL database function I'd have to write.

Looking for pointers, please.
Thanks

Hi gascar welcome to the forums.

See functions fsockopen and the curl library. User submits a form to you, your server then your server connects to another server. Usually a documented protocol is in place for this.
