note 108976 deleted from function.strip-tags by aharvey

Note Submitter: frank at interactinet dot com ---- I used substr() to create a summary... for HTML content this is a problem because of unclosed tags and broken tags (if the content is cut off in the middle of an open or close tag) I came up with this... I am not sure it works 100% of the time, but it seems to do the trick. <?php public static function closetags($html) { // strip fraction of open or close tag from end (e.g. if we take first x characters, we might cut off a tag at the end!) $html = preg_replace('/<[^>]*$/','',$html); // ending with fraction of open tag // put open tags into an array preg_match_all('#<([a-z]+)(?: .*)?(?<![/|/ ])>#iU', $html, $result); $opentags = $result[1]; // put all closed tags into an array preg_match_all('#</([a-z]+)>#iU', $html, $result); $closetags = $result[1]; $len_opened = count($opentags); // if all tags are closed, we can return if (count($closetags) == $len_opened) { return $html; } // close tags in reverse order that they were opened $opentags = array_reverse($opentags); // self closing tags $sc = array('br','input','img','hr','meta','link'); // ,'frame','iframe','param','area','base','basefont','col' // should not skip tags that can have content inside! for ($i=0; $i < $len_opened; $i++) { $ot = strtolower($opentags[$i]); if (!in_array($opentags[$i], $closetags) && !in_array($ot,$sc)) { $html .= '</'.$opentags[$i].'>'; } else { unset($closetags[array_search($opentags[$i], $closetags)]); } } return $html; } ?>
