Simple correction to webscrapper php script and a new one

1. I have a small .php script (around 100 lines) that gathers information from a specific online book store and stores that information in a csv file. The data collected is booktitle, author, price, description etc. The script looks in a text file for the URL's (books) it is to gather information from and then saves this data i a new CSV file. The online store has changed something on their site and the script no longer gets the book descriptions. I need that fixed. 2. I also need a new script done for another online bookstore. That script should gather the exact same information and can likely be based on the existing script. Of course this website looks different that the first one.
