$db = new SQL;
$w=$db->query("SELECT * FROM makers  WHERE 1=1" );if($db->nf()!=0)
{
  for($i=1;$i<=$db->nf();$i++)
    {
   $db->next_record();
   //str_replace("\"","\"\"",$db->p(user_id));
   $user_id=$db->p(user_id);
   //str_replace("\"","\"\"",$db->p(makers));
   $ers=$db->p(ers);
   //str_replace("\"","\"\"",$db->p(comment));
   $comment=$db->p(comment);
  //str_replace("\"","\"\"",$db->p(policy));
   $policy=$db->p(policy);
  //str_replace("\"","\"\"",$db->p(fabu));
   $fabu=$db->p(fabu);
   //str_replace("\"","\"\"",$db->p(fabtime));
   $fabtime=$db->p(fabtime);
$str ="\"$user_id\",\"$ers\",\"$comment\",\"$policy\",\"$fabu\",\"$fabtime\"";
