   ok here it is:

   <?php
   function getWords($text, $limit)
   {
   $array = explode(" ", $text, $limit+1);

   if (count($array) > $limit)
   {
   unset($array[$limit]);
   }
   return implode(" ", $array);
   }
   ?>

   when i use it like this:

   <?php
   $text = "Dies ist ein Text mit fünfzehn Wörtern, von dem wir die ersten vier haben wollen.";

   echo getWords($text, 4);
   ?>

   it works fine, but when i use it like this:

   <?php
   $mycontent = the_content();
   echo getWords($mycontent, 4);
   ?>

   it doesn't work!

   thanks

   <?php
$mycontent = get_the_content();
echo getWords($mycontent, 4);
?>

   the_content() just echoes, whereas get_the_content() allows you to pass the post content to a variable. Also note that no text formatting occurs within get_the_content(), so if you don't like the 'raw' output, try this:

   <?php
$mycontent = getWords(get_the_content(), 4);
echo apply_filters('the_content', $mycontent);
?>

   Final warning: HTML elements can cause problems when excerpting post content, in that there's no way (using the code above) to verify a tag has been closed within your cut.
