User:Plrk/Watchlist RSS feed in PHP

From Meta, a Wikimedia project coordination wiki

Jump to: navigation, search

As User:Sylvain Schmitz/Watchlist RSS feed in PHP is quite outdated, I hacked together a PHP script which uses the API to login, and then fetch the watchlist feed.

There is also a slightly more complicated version that includes diff links.

[edit] Installation

Copy this code into a .php file on your PHP-running web server, after editing your username/password/preferred wiki accordingly. Point your feed aggregator to the PHP script. That's it!
