AMAZON.COM CURL-REST Parser.
Copyright ©2004, Jon Ellis-Jones.
This script is a nice and easy way of parsing REST data from Amazon. The
idea is, you can obtain data about Amazon products for display/storage in
a database, eg. If you had a website about books, you could store amazon's
review or price, images, dimensions etc about each book - the posibilities
are endless.
see: http://www.amazon.com/webservices for more information.
NB : this script works for all amazon subsites, such as amazon.co.uk/amazon.de,
just modify the areas in the script. for more help, see the URL above.

I tried running this script on a curl-enabled server and got the following error message:
Parse error: parse error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or `}` on line 50

hi guys. This script is written for PHP5 only, it will __NOT__ work in PHP4, which I`m guessing is the problem. It has been tested only under Apache 2.x as well, I haven`t had the time to try it under IIS.

If people would find it beneficial for me to write a PHP 4.x version of the same code, I will do so. just let me know here, or via e-mail, and i`ll sort that out for you.

It`s much easier to parse the raw_data with simple_xml, than transforming all in an array.
