substr replacement that does not break words

function snippet($text,$length=64,$tail="...") {
    $text = trim($text);
    $txtl = strlen($text);
    if($txtl > $length) {
        for($i=1;$text[$length-$i]!=" ";$i++) {
            if($i == $length) {
                return substr($text,0,$length) . $tail;
            }
        }
        $text = substr($text,0,$length-$i+1) . $tail;
    }
    return $text;
}
 

This PHP function shortens a string without breaking words.
