Split PHP string

I found this php script:

// separate the tags so as not to break any html $ string = strip_tags ($ string);

if (strlen ($ string)> 500) {

// truncate string
$stringCut = substr($string, 0, 500);

// make sure it ends in a word so assassinate doesn't become ass...
$string = substr($stringCut, 0, strrpos($stringCut, ' ')).'... <a href="/this/story">Read More</a>';  } echo $string;

create webbiedave. Now my question is, how can I tell strrpos to search in space or point?

So, if I limit the line to 22, and if I had something like StackOverFlow - the best site ever → would output StackOverFlow - this ... and if I had something like /qaru.site/ ... - the best site, ever - the output will be only ... because it did not find a space and a length of the string> 22. How can I change this script to cut out the text if I find a point in string /qaru.site/ ... - the best site → become http: // stackoverflow ...?

This will not interrupt the words:

function ShortenText($text, $chars)
{
    $chars = $chars;$text = $text." ";
    $countchars = strlen($text);
    if($countchars > $chars)
    {
        $text = substr($text,0,$chars);
        $text = substr($text,0,strrpos($text,' '));
        $text = $text."...";
    }
    return $text;
}
