PHP Media API Class (YouTube, Flickr, Vimeo, Bitly)

/ Published in: PHP

Originally written by Jason Lengstorf, rewritten by Drew Douglass, packaged into the EnnuiCMS (link above), can be used as standalone class.

Be sure to change or define your constants for PAGE_OBJ_WIDTH and PAGE_OBJ_HEIGHT when using the YouTube method.

<?php

class Media

	static function latestVimeo($username)
	{
		// Load the RSS feed
		$xml = simplexml_load_file('http://vimeo.com/api/v2/'.$username.'/videos.xml');

// Get the first video's ID
		$id = $xml->video[0]->id;

// Output valid XHTML
