1. create a new php direct execution widget
2. add this code:
PHP Code:
<?php
ob_start
();
function 
getNewestXKCD() {
   
$document = new DOMDocument();
   
// Load the HTML document from xkcd.com. The '@' is to suppress error messages (since there is one!).
   
$load = @$document->loadHTMLFile('http://www.xkcd.com/');
   
   
$src '';
   
$title '';
   
$alt '';
   
   
// If we can connect to the site:
   
if ($load) {
      
// Make an array of all of the image tags in the page.
      
$images $document->getElementsByTagName('img');
   
      
// Go through each image tag to until we find the comic.
      
foreach ($images as $image) {
         
// If it's the one with the comic:
         
if (substr($image->getAttribute('src'), 028) == 'http://imgs.xkcd.com/comics/') {
            
$src $image->getAttribute('src');
            
$title $image->getAttribute('title');
            
$alt $image->getAttribute('alt');
            break; 
// We don't need to look anymore.
         
}
      }
   
      
// Create output (no need to use the DOM for this part):
      
$return '<div id="newKXCD" style="text-align:center;"><h1 style="font-size:20px;font-variant:small-caps;font-

family:Lucida, sans-serif;font-weight:bold;">'
.$alt.'</h1>';
      
$return .= '<a href="http://www.xkcd.com" style="size:14pt;color:black;text-decoration:none;"><img src="'.$src.'" 

title="'
.$title.'" alt="'.$alt.'" border="0" /></a></div>';
   }
   
// If we cannot connect to the site, print an error message.
   
else $return '<div id="newKXCD" style="text-align:center"><a href="http://www.xkcd.com">Newest XKCD Comic cannot be 

accessed<br>at this time, please try again later!</a></div>'
;
   return 
$return;

// End function

// Call the function which returns the HTML to display the image
$output getNewestXKCD();

// Oh and: Unexpected end tag : a in http://www.xkcd.com/, line: 48
?>
I changed only echo getNewestXKCD(); to $output = getNewestXKCD(); because $output is the standard outputvariable in the widgets
