Screen Scrapping Information

[ojsimon]

i would like to be able to get amazons price for a product so what ive worked out is that a user types in a product and the script returns a price by converting the users input to a string and adding it to the amazon search url

http://www.amazon.co.uk/s/ref=nb_ss_w_h_/026-7249447-2512412?url=search-alias%3Daps&field-keywords=

String

&Go.x=0&Go.y=0&Go=Go

However i cannot work out how to get the script to get the price from here and saving that as a string.

Thanks

Pull the page down in PHP:

$url = "http://www.amazon.co.uk/s/ref=nb_ss_...ield-keywords=" . $string;
$page = file_get_contents($url);

Then use a regexp to find the price in the source code.

how would you use regular expressions to do this because there are many prices on the page i want the first 1
thanks
