1. Get text.
2. Remove tags
3. Take first <n> characters.
$text="This is some <div>text</div> isn't it interesting. <b>send
money.</b> <i>and beer</i>";
function getSynop($input="", $more_link="", $synop_size=750) {
$syn=substr(strip_tags($text), 0, $synop_size);
return $syn." <a href='".$more_link.."'>more...</a>";
}
hope that helps!
