Market Data Scraper (PHP)

<?php

// Second Life Market Data Scraper
// v1.0.0
// 
// This is an example script using curl to scrape market 
// data off the secondlife.com homepage. You need the curl 
// library compiled with OpenSSL libraries, and write 
// permissions to a cookies.txt file in the same directory 
// as the script. You can accomplish this by creating an 
// empty cookies.txt file and adding group write permission 
// in most cases. You will probably want to modify the 
// script to do something more useful than printing the 
// variables out, like storing them in a database and 
// running the script from a crontab once a day.
