Fatal error: Cannot instantiate non-existent class: simplexmlelement

**traest2** · 18th March 2009, 01:07

I found a little PHP script to get my latest status from Twitter and display it on my site. The script works fine when I run it directly here.

However, when I try to include it on my site here, I get the error: "Fatal error: Cannot instantiate non-existent class: simplexmlelement in /home/.roxysaurus/taestell/v2.travisestell.com/tae-tweet.php on line 23"

I can not figure out why this error is occurring. The site is running PHP5.

Here is the code from tae-tweet.php:

Code:

<h3><span>Latest Tweet</span></h3>

<?php

// Example: Get a single tweet.
$status = getTwitterStatus("taestell");
echo('<div class="footer-element"><blockquote><p>' . $status[0]['message'] . '</p></blockquote> <span class="attrib">â€”<a href="http://twitter.com/taestell">Me</a>, ' . $status[0]['time'] . '</span></div>');

function getTwitterStatus($twitterUser, $howMany = 1) {
  $url = sprintf("http://twitter.com/statuses/user_timeline/%s.xml?count=%d",
      $twitterUser, $howMany);
  $parsed = new SimpleXMLElement(file_get_contents($url));

  $tweets = array();
  foreach($parsed->status as $status) {
    $message = preg_replace("/http:\/\/(.*?)\/[^ ]*/", '<a href="\\0">\\0</a>',
        $status->text);
    $time = niceTime(strtotime(str_replace("+0000", "", $status->created_at)));
    $tweets[] = array('message' => $message, 'time' => $time);
  }
  return $tweets;
}

*/
function niceTime($time) {
  $delta = time() - $time;
  if ($delta < 60) {
    return 'less than a minute ago';
  } else if ($delta < 120) {
    return 'about a minute ago';
  } else if ($delta < (45 * 60)) {
    return floor($delta / 60) . ' minutes ago';
  } else if ($delta < (90 * 60)) {
    return 'about an hour ago';
  } else if ($delta < (24 * 60 * 60)) {
    return 'about ' . floor($delta / 3600) . ' hours ago';
  } else if ($delta < (48 * 60 * 60)) {
    return '1 day ago';
  } else {
    return floor($delta / 86400) . ' days ago';
  }
