main reason - if you sort by first or last name you will lose

this way is index always "linked" to first/last name.

Your point is well taken, but I'm not sorting this. True, the arrays have a common index, which is 0, 1, 2, 3 ...

      [user_id] => Array
          (
              [0] => 6156
              [1] => 7030
              [2] => 656
          )

      [first_name] => Array
          (
              [0] => Diane
              [1] => Fred
              [2] => Helen
          )

      [last_name] => Array
          (
              [0] => Cable
              [1] => Cago
              [2] => Cahalan

But the data is relational, such as: Diane Cable has user id 6156. I collected the data like this (in a loop): $_SESSION['user_id'][] = $value; $_SESSION['first_name'][] = $first_name; $_SESSION['last_name'][] = $last_name; Doing this is fine -- the index is automatic. I thought I could retrieve the data by using: $num_users = count($_SESSION['user_id']); // <--- this works (correct $num_users) for ($i = 0; $i < $num_users; $i++)

    {
    $last_name = $_SESSION['last_name'][$i];
    $first_name = $_SESSION['first_name'][$i];
    echo("<tr><td>$last_name</td><td>$first_name</td></tr>");     }

But that doesn't work. What's really odd is only the first loop works.

I'm thinking register_globals here. In every example you've posted, you've used $last_name and $_SESSION['last_name'] -- but these are the same thing if register_globals is on, and would lead to your posted output with the single characters on the 2nd iteration and nothing after that!

nicely put - that's the one. -- nathan ( nathan@kraya.co.uk ) { Senior Web Developer php + java + flex + xmpp + xml + ecmascript web development edinburgh | http://kraya.co.uk/ }
