Try the below sample. this will surely work.

function limit_to_numwords($text,$no_words){
   $next=substr($text,$no_words,strlen($text));                        
   $spacepos=strpos($next," ");                     
   $desc=substr($text,0,$no_words+$spacepos)."...";
   return $desc;
}

From this, you can get exact full word text from the nearest space character. hope this will help your requirement.

Also, try to call the function as "$this->limit_to_numwords"
