weird php issue

got a php script on server, using http post in game maker to return a string from the script to the game.

it works in basic form where in the php i just put
echo "hello";

the game shows message "hello" as you would expect.

now im getting some id (int) values from a mysql db and making a string with ids seperated by commas for example "1,2,3,5,7,8,9"

i use this:
Code:
$rett="";
 if ($result)
  {
  if (mysqli_num_rows($result)>0)
   {
   while ($row = mysqli_fetch_assoc($result))
    {
    $rett = $rett . strval($row["id"]) . ",";
    }   
   }
  }

echo $rett;
But it doesnt return anything!

now if i change it to
echo "Wtf".$rett;

it returns "Wtf1,2,3,5,7"

so why is this weird problem? Why wont it return "1,2,3,5,7"?

Ive also tried
echo strval($rett);

deosnt work either...
