$teaser = strip_tags($content); $teaser = substr($teaser, 0, 100); $teaser .= '...'; // Nice touch to have a '...' on the end :) I can't think of a way of keeping HTML tags but ensuring you don't cut off half way through one - I suppose you could do it by scanning along the string character by character keeping track ofwhether or not you have encountered a < without a matching >, then if you get to the end and you are half way through a tag running back to the start of the tag and deleting from there. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
