PHP RSS Feed Generator API

Very light weight PHP API encapsulating entire RSS-2 specification, the worldwide standard at this moment for generating RSS feeds.

API only requires PHP7.1+ and comes with a class for each RSS tag, all belonging to Lucinda\RSS namespace, each implementing Tag interface. Following are factually mandatory:

Class	Description
RSS	Encapsulates rss tag, the grand holder of your RSS feed
Channel	Encapsulates channel tag, child of rss, containing your RSS feed description
Item	Encapsulates item tag, child of channel, containing an article in your RSS feed

Simple example:

$channel = new \Lucinda\RSS\Channel("Lucinda Framework", "https://www.lucinda-framework.com", "Current headlines from Lucinda Framework");
$channel->addItem(new \Lucinda\RSS\Item("STDOUT MVC API", "STDOUT MVC API was upgraded to a new version"));
$channel->addItem(new \Lucinda\RSS\Item("STDERR MVC API", "STDERR MVC API was upgraded to a new version"));
$rss = new \Lucinda\RSS\RSS($channel);
echo $rss; // displays RSS feed

API enjoys 100% unit test coverage for its classes and methods, reproductible in console by running:

composer update
php test.php
