Answer 1

This one is short and takes word boundary into account, it doesn't use loops which makes it very efficient

function truncate($str, $chars, $end = '...') {
    if (strlen($str) <= $chars) return $str;
    $new = substr($str, 0, $chars + 1);
    return substr($new, 0, strrpos($new, ' ')) . $end;
}

Usage:

truncate('My string', 5); //returns: My...
