Re: need an idea...

You would probably need some API plugins to search other websites. I've seen some people open socket connections, open the site and read the raw HTML from the socket into a buffer and then parse out the information that way. I don't know if PHP was really developed for such a purpose? Maybe you can get the source code for htdig. And I think pricewatch requires that the external companies notify/register/contact them. They don't necessarily scane evry site out there, otherwise you might see "Best Buy" and "CompUSA" right? -Brad > Hi, > > I'm wondering how can I write some php script to scan a couple of(or more) > websites to find out the lowest price of a particular item? what is the idea > behind this kind of programing? > > Also, I am always wondering how does the pricewatch website works?
