I put the answer of John Conde in a method:

function softTrim($text, $count, $wrapText='...'){

    if(strlen($text)>$count){
        preg_match('/^.{0,' . $count . '}(?:.*?)\b/siu', $text, $matches);
        $text = $matches[0];
    }else{
        $wrapText = '';
    }
    return $text . $wrapText;
}

Examples:

echo softTrim("Lorem Ipsum is simply dummy text", 10);
/* Output: Lorem Ipsum... */

echo softTrim("Lorem Ipsum is simply dummy text", 33);
/* Output: Lorem Ipsum is simply dummy text */

echo softTrim("LoremIpsumissimplydummytext", 10);
/* Output: LoremIpsumissimplydummytext... */
