Hi, I would like to develope my own backlink checker, rss builder and rss pinger scripts. I know how make a php rss builder for inserting links and agregate all in a valide feed...but Where can I find an API / script / class / whatever that allows me to ping services and return the response? I don't know if I'm being clear here but I guess its pretty straight forward what I want to do. I would also like to build a backlink checker but the only ideia that comes to my mind is to scrape with the DOM the returned html of a google query and filter it (maybe caching the pages one by one on the drive and filtering it) is there any other way? Also I would like to have all this wrapped in some sorte of php/api/class proxie stuff so I can be shielded/ never b*nned from the rss ping servers/services basicly I'm a very new programmer learning and I want to build my own bulkping site can someone point me in the right directions ? ebooks for this / tutorials scripts? Please?
