Hi gang:

As strange as it may seem, but when session variables are passed to another
page (i.e., used) you cannot extract ALL OF THEM using a loop when the
variable names you are using are the same as the SESSION index's names.

In other words, you cannot do this:

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>");
}

But you can do this:

for ($i = 0; $i < $num_users; $i++)
{
$last = $_SESSION['last_name'][$i];
$first = $_SESSION['first_name'][$i];
echo("<p>$last $first</p>");
}

See the difference?

This was a crazy one.

Now, someone show me where that is documented?

As several of us have suggested now, it's got to be register_globals.
That would make the following blocks of code equivalent:

<?php

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>");
}

for ($i = 0; $i < $num_users; $i++)
{
$_SESSION['last_name'] = $_SESSION['last_name'][$i];
$_SESSION['first_name'] = $_SESSION['first_name'][$i];
echo("<p>{$_SESSION['last_name']} {$_SESSION['first_name']}</p>");
}

?>
