Get latest twitter updates -- PHP

A Twitter class to get the latest twitter updates.  The class uses twitter's user_timeline feed.

Twitter.php

<?php

class Twitter
{

 public $tweets_title = array();
 public $tweets_desc = array();
 public $tweets_published = array();
 public $tweets_link = array();

        public function __construct($username) {
  
  //Load tweets from user timeline.
  $result = simplexml_load_file("http://twitter.com/statuses/user_timeline/".$username.".rss");
  
  //Iteration of XML object
  foreach(get_object_vars($result) as $property => $value) {
   
   //Iteration of each Item
   if(isset($value->item)) {
    for ($iterator = 0; $iterator < count($value->item); $iterator++) {
     $this->tweets_title[$iterator] = $value->item[$iterator]->title;
     $this->tweets_desc[$iterator] = $value->item[$iterator]->description;
     $this->tweets_published[$iterator] = $value->item[$iterator]->pubDate;
     $this->tweets_link[$iterator] = $value->item[$iterator]->link;     
    }
   }
  }
 }

        public function getTweetTitle($number) {
  return $this->tweets_title[$number][0];  
 }
 
 public function getTweetDescription($number) {
  return $this->tweets_desc[$number][0];
 }
 
 public function getTweetPublishedDate($number) {
  return $this->tweets_published[$number][0];
 }
 
 public function getTweetLink($number) {
  return $this->tweets_link[$number][0];
 }
}

?>

index.php

<?php

require_once 'Twitter.php';

//Replace MY_USERNAME with twitter username
$tweet = new Twitter('MY_USERNAME');

/**
 * To get the tweet details
 * Change param to get the tweet number.
 * eg. $tweet->getTweetTitle(5) will get you the 6th tweet
 */

echo "Tweet : " . $tweet->getTweetTitle(0);
echo "Description : " . $tweet->getTweetDescription(0);
echo "Link : " . $tweet->getTweetLink(0);
echo "Published Date : " . $tweet->getTweetPublishedDate(0);

?>

That is it. Just change the MY_USERNAME in the index.php file with the twitter username.
