How to display Twitter updates using PHP (and without using curl)

twitter.php

<?php
$doc = new DOMDocument();
 
# load the RSS -- replace 'lylo' with your user of choice
if($doc->load('http://twitter.com/statuses/user_timeline/lylo.rss')) {
  echo "<ul>\n";
 
  # number of <li> elements to display.  20 is the maximum
  $max_tweets = 10;    
 
  $i = 1;
  foreach ($doc->getElementsByTagName('item') as $node) {
    # fetch the title from the RSS feed. 
    # Note: 'pubDate' and 'link' are also useful (I use them in the sidebar of this blog)
    $tweet = $node->getElementsByTagName('title')->item(0)->nodeValue;
 
    # the title of each tweet starts with "username: " which I want to remove
    $tweet = substr($tweet, stripos($tweet, ':') + 1);   
 
    # OPTIONAL: turn URLs into links
    $tweet = preg_replace('@(https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?)@', 
          '<a href="$1">$1</a>', $tweet);
 
    # OPTIONAL: turn @replies into links
    $tweet = preg_replace("/@([0-9a-zA-Z]+)/", 
          "<a href=\"http://twitter.com/$1\">@$1</a>", 
          $tweet);
 
    echo "<li>". $tweet  . "</li>\n";
 
    if($i++ >= $max_tweets) break;
  }
  echo "</ul>\n";
} 
?>
