The Developer Tutorials site has posted a new article covering the creation of a small application that can help you scrape content from a remote page and pull it into your script.

In this tutorial you will learn how to build a PHP script that scrapes links from any web page.

You'll learn to use cURL, the DOM functions, XPath and a bit of MySQL to get the job done. It's nice to see that they also include a section looking at one of the more touchy aspects of web page scraping - "is it legal?"
