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?
