note 117351 added to function.strip-tags

Hi, I havee a problem with this function. I want use this symbol in my text ( < ), but it doesn't work because I added character stuck to that symbol. Exemple : <?php $test = '<p><span style="color: #ff0000; background-color: #000000;">Complex</span> <span style="font-family: impact,chicago;">text <50% </span> <a href="http://exempledomain.com/"><em>with</em></a> <span style="font-size: 36pt;"><strong>tags</strong></span></p>'; echo strip_tags('$test'); // Outputs : Complex text ?> I made a function for this : Function: <?php function strip_tags_review($str, $allowable_tags = '') { preg_match_all('/<(.+?)[\s]*\/?[\s]*>/si', trim($allowable_tags), $tags); $tags = array_unique($tags[1]); if(is_array($tags) AND count($tags) > 0) { $pattern = '@<(?!(?:' . implode('|', $tags) . ')\b)(\w+)\b.*?>(.*?)</\1>@i'; } else { $pattern = '@<(\w+)\b.*?>(.*?)</\1>@i'; } $str = preg_replace($pattern, '$2', $str); return preg_match($pattern, $str) ? strip_tags_review($str, $allowable_tags) : $str; } echo strip_tags_review($test); // Outputs: Complex text <50% with tags echo strip_tags_review($test, '<a>'); // Outputs: Complex text <50% <a href="http://exempledomain.com">with</a> tags ?> ---- Server IP: 72.52.91.14 Probable Submitter: 91.213.82.241 ---- Manual Page -- http://php.net/manual/en/function.strip-tags.php Edit -- https://master.php.net/note/edit/117351 Del: integrated -- https://master.php.net/note/delete/117351/integrated Del: useless -- https://master.php.net/note/delete/117351/useless Del: bad code -- https://master.php.net/note/delete/117351/bad+code Del: spam -- https://master.php.net/note/delete/117351/spam Del: non-english -- https://master.php.net/note/delete/117351/non-english Del: in docs -- https://master.php.net/note/delete/117351/in+docs Del: other reasons-- https://master.php.net/note/delete/117351 Reject -- https://master.php.net/note/reject/117351 Search -- https://master.php.net/manage/user-notes.php
