Displaying Logged in Content on a Website

问题

I'm not quite sure how to describe this in words without making it overly complex, so here is basically what I want to happen:

1. The user goes to my website, let's say: www.example.com/
2. The server goes to another website, example2.com, which has a field where their users should enter their username and password
3. The server inputs the username and password automatically, and then gets redirected to a "user section" of the site.
4. The server clicks on one of the links on the sidebar, and gets sent to another page "user section".
5. Then, the site grabs all of the content on this page, and displays it on example.com

The reason I am attempting to do this is to create an RSS feed out of a website that has a username and password part where the user has to log in. I have not seen a RSS creating website that enables you to do this, which is why I am trying to accomplish it this way. However, if anyone knows of a RSS website that will enable you to do this, that would also be great.

Thanks for any help!

It sounds like you might be looking for cURL and cookiejar:

http://curl.haxx.se/libcurl/php/examples/cookiejar.html

This will allow you to programmatically login to a site, keep a session open, and then access the login protected content. Once you get the page contents, then you can use DomDocument (http://us2.php.net/manual/en/domdocument.loadhtml.php) to access the content you need and turn it into RSS data.

Edit: if the website uses form keys, like many do, this will require extra work to extract the form key from the login page and add it to the login POST
