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.
