Hi gang:
Apparently, there's something going on here that I don't understand --
this happens far too often these days.
Here's a print_r($_SESSION); of the session arrays I'm using:
[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
The following is how I tried to access the data contained in the
$_SESSION arrays:
$num_users = count($_SESSION['user_id']);
for ($i = 0; $i < $num_users; $i++)
{
$last_name = $_SESSION['last_name'][$i];
$first_name = $_SESSION['first_name'][$i];
echo("<p>$last_name, $first_name</p>");
}
The only thing that came out correct was the first echo. The remaining
echos had no values for $first_name or $last_name.
What's happening here?
Cheers,

PS: I'm open to other suggestions as to how to do this.
Why don't you echo what you are trying to access for each loop
for ($i = 0; $i < $num_users; $i++)
{
print_r($_SESSION['last_name'][$i]);
print_r($_SESSION['first_name'][$i]);
}
Does the above return to you what you would expect?
An alternate to what you are doing here would be this.
foreach ( $_SESSION['user_id'] AS $i=>$id)
{
print_r($id);
print_r($_SESSION['last_name'][$i]);
print_r($_SESSION['first_name'][$i]);
}
How about this?
