hi

i'm using the following:

<?php
$doc = new DOMDocument();
$doc->load('http://twitter.com/statuses/user_timeline/XXXXXX.rss');
$arrFeeds = array();

foreach ($doc->getElementsByTagName('item') as $node) {
    $itemRSS = array ( 
        'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
        'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
        'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
        'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue
    );
    array_push($arrFeeds, $itemRSS);
}

for($i=0;$i<=3;$i++) {
    $tweet=substr($arrFeeds[$i]['title'],17); 
    $tweetDate=strtotime($arrFeeds[$i]['date']);
    $newDate=date('G:ia l F Y ',$tweetDate);
    if($i==0) { $b='style="border:none;"'; }
    $tweetsBox.='<div class="tweetbox" ' . $b . '>
    <div class="tweet"><p>' . $tweet . '</p>
    <div class="tweetdate"><a href="http://twitter.com/XXXXXX">@' . $newDate .'</a></div>
    </div>
    </div>';
} 

return $tweetsBox;
?>

to return the 4 most recent tweets from a given timeline (XXXXX is the relevant feed)

It seems to work fine but i've recently been getting the following error sporadically:

PHP error debug Error: DOMDocument::load(http://twitter.com/statuses/user_timeline/XXXXXX.rss) [domdocument.load]: failed to open stream: HTTP request failed! HTTP/1.1 502 Bad Gateway

I've read that the above code is dependant on Twitter beign available and I know it gets rather busy sometimes. Is there either a better way of receiving twits, or is there any kind of error trapping i could do to just to display "tweets are currently unavailable..." ind of message rather than causing an error. I'm usnig ModX CMS so any parse error kills the site rather than just ouputs a warning.

thanks.
