note 94948 added to function.strip-tags

Inspired by previous Steve strip_only() posted function I've developed a more extensive function to strip specified tags as long as every single HTML tag from string (hope every tag is on the list) Works for HTML and XHTML tag versions, also for HTML comments, and is ready for the new HTML5 tags to be released <?php /** * Removes HTML tags from string. * If no tags specified in $tags removes every HTML tag on the string. * * @param string $string * @param mixed $tags * @return string */ function stripHtml($string, $tags = '') { if ($tags == '') { //current (HTML5) and previous HTML tags $tags = array( '!--', '!doctype', 'a', 'abbr', 'acronym', 'address', 'applet', 'area', 'article', 'aside', 'audio', 'b', 'base', 'basefont', 'bdo', 'big', 'blockquote', 'body', 'br', 'button', 'canvas', 'caption', 'center', 'cite', 'code', 'col', 'colgroup', 'command', 'datalis', 'dd', 'del', 'details', 'dialog', 'dfn', 'div', 'dir', 'dl', 'dt', 'em', 'embed', 'fieldset', 'figure', 'font', 'footer', 'form', 'frame', 'frameset', 'h1', 'h2', 'h3', 'h4', 'h5', 'h6', 'head', 'header', 'hgroup', 'hr', 'html', 'i', 'frame', 'img', 'input', 'ins', 'isindex', 'keygen', 'kbd', 'label', 'legend', 'li', 'link', 'map', 'mark', 'menu', 'meta', 'meter', 'nav', 'noframes', 'noscript', 'object', 'ol', 'optgroup', 'option', 'output', 'p', 'param', 'pre', 'progress', 'q', 'rp', 'rt', 'ruby', 's', 'samp', 'script', 'section', 'select', 'small', 'source', 'span', 'strike', 'strong', 'style', 'sub', 'sup', 'table', 'tbody', 'td', 'textarea', 'tfoot', 'th', 'thead', 'time', 'title', 'tr', 'tt', 'u', 'ul', 'var', 'video', 'xmp' ); } if (!is_array($tags)) { $tags = (strpos($tags, '>') !== false ? explode('>', str_replace(array('<', '/'), '', trim($tags))) : array(trim($tags))); if (end($tags) == '') { array_pop($tags); } } foreach($tags as $tag) { $tag = strtolower(trim($tag)); switch ($tag) { case '!comment': case 'comment': case '!--': $string = preg_replace('#<!--[^(-->)]*-->#is', '', $string); break; case '!doctype': case 'doctype': $string = preg_replace('#<!DOCTYPE[^>]*>#is', '', $string); break; default: $string = preg_replace('#</?'.$tag.'[^>]*/?>#is', '', $string); break; } } return $string; } ?> Hoping someone can find this useful as I did ---- Server IP: 130.206.1.5 Probable Submitter: 88.6.20.121 ---- Manual Page -- http://www.php.net/manual/en/function.strip-tags.php Edit -- https://master.php.net/note/edit/94948 Del: integrated -- https://master.php.net/note/delete/94948/integrated Del: useless -- https://master.php.net/note/delete/94948/useless Del: bad code -- https://master.php.net/note/delete/94948/bad+code Del: spam -- https://master.php.net/note/delete/94948/spam Del: non-english -- https://master.php.net/note/delete/94948/non-english Del: in docs -- https://master.php.net/note/delete/94948/in+docs Del: other reasons-- https://master.php.net/note/delete/94948 Reject -- https://master.php.net/note/reject/94948 Search -- https://master.php.net/manage/user-notes.php
