 March 2008 Number 7 Prize: One copy of Delphi for PHP |
Retrieving Web pages from remote sites is a relatively easy task in PHP. If you want to crawl a site to search for something in its pages, you only need to retrieve the site pages, use some regular expressions to extract the site links, and retrieve the linked pages until all pages were followed. However, if some pages can only be accessed by authenticated users, the problem is no longer so simple. This package provides a more complete solution to the problem of crawling site pages by automatically authenticating, so it can access all pages restricted to logged users. Manuel Lemos |
