Getting Remote Webpage Info Using PHP

If you run any website that accepts submitted links, be it a tutorial website, a directory or a bookmarking site, you may find it useful to automatically retrieve information about a URL. Wouldn't it be nice if you ran a web directory and you could bring up the title, keywords and description of a URL without the user having to enter it? This tutorial shows you how this can be achieved via PHP. Firstly we need to set the URL of the web page. Note that it must contain the http prefix as we are going to load some data in through a HTTP file stream.
