I have a web site and google likes to count the inbound links. I have set
up a way for people to add links from my site to theirs, however I would
like to check whether they have linked back to my site. I ask them to
nominate where the link back page is, and I could check this manually. But
you could probably use curl to grab the source for the page then use a regex
to see if your domain is found maybe something like
if(preg_match("/www\.domain\.com/is")) // match found
else // not found
dont quote me on the regex as i am not very good with regex, also you would
want a button in the
