You should use Codeigniter text helper:

$this->load->helper('text'); // add this to the the function or to the constructor

$string .= '<p>' . e(word_limiter(strip_tags($article->content), $numwords)) . '</p>';

In this article you can find many useful codeigniter text functions

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"
