My error, if produced. Cable, Diane a, i While print_r($_SESSION); JUST BEFORE IT produced: [user_id] => Array

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

[first_name] => Array

    (
        [0] => Diane
        [1] => first name
        [2] => Helen
    )

[last_name] => Array

Now, what wrong with this picture? Cheers, tedd

in this case.. what's happened is: $_SESSION['first_name'] is a reference to a variable $first (or whatever is in your for loop) $_SESSION['last_name'] is a reference to a variable $last (or whatever is in your for loop) when you've set $last and $first to string's in the for loop it's passed the variable by reference back to $_SESSION['first_name'] and $_SESSION['last_name'] as strings; when it hit's the second iteration on the for loop it now has strings to deal with so uses the $key (holding integer 1 at this stage) as a string offset thus giving you the second character (offset [1]) of the string variables $last/$first. now set to 'cable'/'diane' thus giving you the 'a'/'i'. when it does pass three there is no offset [2] so gives you nothing. *phew* reproduce code! <?php $userids = array('6156','1234','8867'); $first = array('Diane','Big','Joe'); $last = array('Cable','Ron','Dirt'); function save_to_session( ) { global $userids , $first , $last; $_SESSION['user_id'] = &$userids; $_SESSION['first_name'] = &$first; $_SESSION['last_name']= &$last; } save_to_session( ); print_r( $_SESSION ); $num_users = count($_SESSION['user_id']); for ($i = 0; $i < $num_users; $i++) {

    $first = $_SESSION['first_name'][$i];
    $last = $_SESSION['last_name'][$i];
    echo "$last, $first\n";
