PHP過濾post、get敏感性資料的例子

/** * 批量過濾post,get敏感性資料 * by bbs.it-home.org */ if (get_magic_quotes_gpc()) { $_GET = stripslashes_array($_GET); $_POST = stripslashes_array($_POST); } function stripslashes_array(&$array) { while(list($key,$var) = each($array)) { if ($key != 'argc' && $key != 'argv' && (strtoupper($key) != $key || ''.intval($key) == "$key")) { if (is_string($var)) { $array[$key] = stripslashes($var); } if (is_array($var)) { $array[$key] = stripslashes_array($var); } } } return $array; } //-------------------------- // 替換HTML尾標籤,為過濾服務 //-------------------------- function lib_replace_end_tag($str) { if (empty($str)) return false; $str = htmlspecialchars($str); $str = str_replace( '/', "", $str); $str = str_replace("\\", "", $str); $str = str_replace(">", "", $str); $str = str_replace("<", "", $str); $str = str_replace("", "", $str); $str = str_replace("", "", $str); $str=str_replace("select","select",$str); $str=str_replace("join","join",$str); $str=str_replace("union","union",$str); $str=str_replace("where","where",$str); $str=str_replace("insert","insert",$str); $str=str_replace("delete","delete",$str); $str=str_replace("update","update",$str); $str=str_replace("like","like",$str); $str=str_replace("drop","drop",$str); $str=str_replace("create","create",$str); $str=str_replace("modify","modify",$str); $str=str_replace("rename","rename",$str); $str=str_replace("alter","alter",$str); $str=str_replace("cas","cast",$str); $str=str_replace("&","&",$str); $str=str_replace(">",">",$str); $str=str_replace("<","<",$str); $str=str_replace(" ",chr(32),$str); $str=str_replace(" ",chr(9),$str); $str=str_replace(" ",chr(9),$str); $str=str_replace("&",chr(34),$str); $str=str_replace("'",chr(39),$str); $str=str_replace(" ",chr(13),$str); $str=str_replace("''","'",$str); $str=str_replace("css","'",$str); $str=str_replace("CSS","'",$str); return $str; } 複製代碼
