Link-back script

Recommended Posts

Hi all some has asked me to right a script for them but i'm not shore what they want this is what they said to me.... i want something that will give a code of my banner...and members put that code on their websites ...then something checks to see if the code is really there..then it will allow that member to put his link on my site. Question 1...Is there a pre-made script for this already?Question 2...If not i assume i would use a cron job?Question 3...How can i make a script check another site's content? Thanks

You can use DOM to get the html page over the network and parse them to find the exact node of your advertisement node. and to fetch users from database you are going to need CRON.
