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
(
[0] => Cable
[1] => CagoEsogs-temp (forum)
[2] => Cahalane
)
Now, what wrong with this picture?

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";
}
?>
