PHP Limit text to two lines & add dots at the end

This guy: https://stackoverflow.com/a/7239020/2453678 posted a great answer here: http://jsfiddle.net/imoda/REs2Q/

Basically, if you want a elegant solution, counting the number of characters is out of question, as each letter has different weight.

The question is:

span {
    display: inline-block;
    border: black 1px solid;
    width: 200px;
    height: 40px;
    overflow: hidden;
}

How to modify the above code, so at the end, if the string is shortened, three '.' are added?

I've coded a simple function in PHP.

function limit_text($input, $n){
    $array = preg_split('~\R+~', $input);       // Split by newline(s)
    $array = array_slice($array, 0, $n);        // Get the first n parts
    $output = implode('<br>', $array) . '...';  // Implode and add some dots
    return $output;
}

Here's how you use it:

$str = 'span {
    display: inline-block;
    border: black 1px solid;
    width: 200px;
    height: 40px;
    overflow: hidden;
}';

echo '<pre>' . limit_text($str, 2); . '</pre>';
