放到公用调用文件(如conn数据库链接文件),对所有GET或POST的数据进行过滤特殊字符串,以实现简单有效的SQL注入过滤

复制代码 代码如下:
Function inject_check($sql_str) {
 return eregi('select|insert|and|or|update|delete|\'|\/\*|\*|\.\.\/|\.\/|union|into|load_file|outfile', $sql_str);
}
if (inject_check($_SERVER['QUERY_STRING'])==1 or inject_check(file_get_contents("php://input"))==1){
 //echo "警告 非法访问!";
 header("Location: Error.php");
}
