Session start in Joomla using a while loop

Question

I have 2 databases, one with Joomla installed and the other with my personal data.

I need to work contemporaneously with these 2 databases.

Now I do a while into my DB with this query:

 $query="Select * From lista where user_id='$id'"; 
 $result = mysql_query($query) or die(mysql_error());
 while($row=mysql_fetch_array($result))
 {
     $ID_STRUCTURE=$row['ID'];
     ECHO '<P>Modifica <a href="..../test/index.php/modifica">'.$row['struttura'].'</P>';
     $session =& JFactory::getSession();
     $session->set( 'myvar', $ID_STRUCTURE );
 }

When I go on the page /test/index.php/modifica I use this code:

  $session =& JFactory::getSession();
  $myvar= $session->get('myvar');
  echo $myvar;

I must obtain only the $ID_STRUCTURE of the correspondent $row['struttura'].

If I use an array in the while and a foreach in the other page /test/index.php/modifica, I obtain all the values.

How can I fix it?

Of course, because you are always overwrite that in your loop. You need to create an array, or make the key to be unique.

while ($row = mysqli_fetch_array($result)) {
    $ID_STRUCTURE = $row['ID'];
    ECHO '<P>Modifica <a href="..../test/index.php/modifica">' . $row['struttura'] . '</P>';
    $myvarArray[] = $ID_STRUCTURE;
}
$session = & JFactory::getSession();
$session->set('myvar', $myvarArray);

Use mysqli or PDO instead mysql functions since they are deprecated.
