Default first x words

I've written a some scripts to pull out posts from specific forums to display on non-vb pages, but am having trouble cropping the sentence for display on the article listing page. If you want to see my problem, go here http://www.numbmonkey.com. Basically, I want the title and the first x words displayed. I've tried two different functions to crop at x characters or x words, but they have a tendancy to cut URL links in half. How can I crop after so many words with busting the vbulletin URL tags.

Here are the two scripts I tried (first one adds a nice "..." after crop):

PHP Code:
function CropSentence ($strText$intLength$strTrail) {
 
$wsCount 0;
 
$intTempSize 0;
 
$intTotalLen 0;
 
$intLength $intLength strlen($strTrail);
 
$strTemp "";
 if (
strlen($strText) > $intLength) {
  
$arrTemp explode(" "$strText);
  foreach (
$arrTemp as $x) {
   if (
strlen($strTemp) <= $intLength$strTemp .= " " $x;
  }
  
$CropSentence $strTemp $strTrail;
 } else {
  
$CropSentence $strText;
 }
 return 
$CropSentence;

and the second one crops by words but doesn't add the "...":
PHP Code:
function firstwords($str,$wordcount) {
$words=preg_split('/([\s.,;]+)/',$str,$wordcount+1,PREG_SPLIT_DELIM_CAPTURE);
array_pop($words);
return(
implode('',$words));

Any help on this would be greatly appreciated!

Thanks,
-Matt
