[PHP] problem z kodem Opcje

[wazniak]

<?php wpn_content_limit(get_the_content(),140); ?>
Chodzi mi o ten kod, jak potrzeba więcej to napiszcie wkleję (IMG:style_emoticons/default/winksmiley.jpg)
Sprawa jest prosta, chcę żeby pokazywał on na przykład od 60 znaku do 140 znaku a niestety nie wiem jak się do tego zabrać.
