note 97990 added to function.htmlspecialchars

Updated my form data parser. I found it easier to use a regular expression to check and see if any previously encoded data exists, then decode it repeatedly until there is none left, then re-encode it. <?php function formspecialchars($var) { $pattern = '/&(#)?[a-zA-Z0-9]{0,};/'; if (is_array($var)) { // If variable is an array $out = array(); // Set output as an array foreach ($var as $key => $v) { $out[$key] = formspecialchars($v); // Run formspecialchars on every element of the array and return the result. Also maintains the keys. } } else { $out = $var; while (preg_match($pattern,$out) > 0) { $out = htmlspecialchars_decode($out,ENT_QUOTES); } $out = htmlspecialchars(stripslashes(trim($out)), ENT_QUOTES,'UTF-8',true); // Trim the variable, strip all slashes, and encode it } return $out; } ?> ---- Server IP: 64.71.164.2 Probable Submitter: 158.83.184.98 ---- Manual Page -- http://www.php.net/manual/en/function.htmlspecialchars.php Edit -- https://master.php.net/note/edit/97990 Del: integrated -- https://master.php.net/note/delete/97990/integrated Del: useless -- https://master.php.net/note/delete/97990/useless Del: bad code -- https://master.php.net/note/delete/97990/bad+code Del: spam -- https://master.php.net/note/delete/97990/spam Del: non-english -- https://master.php.net/note/delete/97990/non-english Del: in docs -- https://master.php.net/note/delete/97990/in+docs Del: other reasons-- https://master.php.net/note/delete/97990 Reject -- https://master.php.net/note/reject/97990 Search -- https://master.php.net/manage/user-notes.php
