note 105589 added to function.strip-tags

phpjs.org has a better version of strip_tags. I've taken their javascript and translated it to PHP: function my_strip_tags ($input, $allowed) { // Strips HTML and PHP tags from a string // // version: 1107.2516 // discuss at: http://phpjs.org/functions/strip_tags // + original by: Kevin van Zonneveld // + improved by: Luke Godfrey // + input by: Pul // + bugfixed by: Kevin van Zonneveld // + bugfixed by: Onno Marsman // + input by: Alex // + bugfixed by: Kevin van Zonneveld // + input by: Marc Palau // + improved by: Kevin van Zonneveld // + input by: Brett Zamir // + bugfixed by: Kevin van Zonneveld // + bugfixed by: Eric Nagel // + input by: Bobby Drake // + bugfixed by: Kevin van Zonneveld // + bugfixed by: Tomasz Wesolowski // + input by: Evertjan Garretsen // + revised by: Rafał Kukawski // * example 1: strip_tags('<p>Kevin</p> <b>van</b> <i>Zonneveld</i>', '<i><b>'); // * returns 1: 'Kevin <b>van</b> <i>Zonneveld</i>' // * example 2: strip_tags('<p>Kevin <img src="someimage.png" onmouseover="someFunction()">van <i>Zonneveld</i></p>', '<p>'); // * returns 2: '<p>Kevin van Zonneveld</p>' // * example 3: strip_tags("<a href='http://kevin.vanzonneveld.net'>Kevin van Zonneveld</a>", "<a>"); // * returns 3: '<a href='http://kevin.vanzonneveld.net'>Kevin van Zonneveld</a>' // * example 4: strip_tags('1 < 5 5 > 1'); // * returns 4: '1 < 5 5 > 1' // * example 5: strip_tags('1 <br/> 1'); // * returns 5: '1 1' // * example 6: strip_tags('1 <br/> 1', '<br>'); // * returns 6: '1 1' // * example 7: strip_tags('1 <br/> 1', '<br><br/>'); // * returns 7: '1 <br/> 1' // making sure the $allowed arg is a string containing only tags in lowercase (<a><b><c>) $allowed = preg_match_all('/<[a-z][a-z0-9]*>/', $allowed, $matches); $allowed = implode('', $matches[0]); // Get rid of comments and php tags $commentsAndPhpTags = '/<!--[\\s\\S]*?-->|<\\?(?:php)?[\\s\\S]*?\?>/'; $input = preg_replace($commentsAndPhpTags, '', $input); // Get rid of all but allowed HTML tags $tags = '/<\\/?([a-z][a-z0-9]*)\\b[^>]*>/'; $input = preg_replace_callback($tags, create_function('$matches', 'return (strpos("' . $allowed .'", "<{$matches[1]}>")===FALSE) ? "" : $matches[0];'), $input); return $input; } ---- Server IP: 192.41.42.26 Probable Submitter: 198.151.13.80 ---- Manual Page -- http://www.php.net/manual/en/function.strip-tags.php Edit -- https://master.php.net/note/edit/105589 Del: integrated -- https://master.php.net/note/delete/105589/integrated Del: useless -- https://master.php.net/note/delete/105589/useless Del: bad code -- https://master.php.net/note/delete/105589/bad+code Del: spam -- https://master.php.net/note/delete/105589/spam Del: non-english -- https://master.php.net/note/delete/105589/non-english Del: in docs -- https://master.php.net/note/delete/105589/in+docs Del: other reasons-- https://master.php.net/note/delete/105589 Reject -- https://master.php.net/note/reject/105589 Search -- https://master.php.net/manage/user-notes.php
