here is my version of fill_paragraphs, it will wrap at the first space before 
the 80th column of the incoming text and make it real nice
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

function fill_paragraphs($text) {
   set_time_limit(0);
   $break="\n";

   $lines = explode("\n", $text);
   $lines_size = sizeof($lines);

   $i = 0;

   $wrap=80;
   while ($i < $lines_size) {
      if (strlen($lines[$i]) <= $wrap) {
         $result[] = $lines[$i];
         $i++;
      } else {
        $wrap=80;
        while(  ($wrap > 0 ) &&
                (substr($lines[$i], $wrap,1) != " ")
             ){
                $wrap--;
        }
        if ( $wrap == 0 ) {$wrap =80;}

         $result[] = substr($lines[$i], 0, $wrap);
         $lines[$i] = substr($lines[$i], $wrap + 1, strlen($lines[$i]) - $wrap);
      }
   }

   return implode($break, $result);
}
