Answer 1

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

Answer 2

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"
