twitterss is a simple PHP script to cross post RSS feed to the twitter (like this one). Posting rules are made with regexps, so you can extract pretty anything from feed.
git clone https://github.com/hom3chuk/twitterss.git #clone into sources
cd twitterss #change directory
composer install #install dependencies. If you do not have composer, go to https://getcomposer.org/download/
vim config.php #add twitter API params and RSS URL to config
php twitterss.php #run! Now you can add this call to CRON, for automated updates.
