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,
tedd
PS: I'm open to other suggestions as to how to do this.
ehh? i think everybody's looking too hard at this..
[tested - works]
<?php
$_SESSION['user_id'][] = '6156';
$_SESSION['first_name'][] = 'Diane';
$_SESSION['last_name'][] = 'Cable';
$_SESSION['user_id'][] = '1234';
$_SESSION['first_name'][] = 'Big';
$_SESSION['last_name'][] = 'Ron';
$_SESSION['user_id'][] = '8867';
$_SESSION['first_name'][] = 'Joe';
$_SESSION['last_name'][] = 'Dirt';
print_r( $_SESSION );
foreach( $_SESSION['user_id'] as $index => $value ) {
$last_name = $_SESSION['last_name'][$index];
$first_name = $_SESSION['first_name'][$index];
echo $last_name . ',' . $first_name . PHP_EOL;
}
?>

I need to re-address this.. tedd your original code works fine over
here; as does the code I sent you, and the code jay submitted first..
do us a favour, copy and paste exactly what I just handed through and
run it; are the results correct?
next up, is you're real code somewhat bulkier and more too it? if so
then something runs in my head that you should check if you already have
a $last_name / $first_name somewhere earlier, and if you do where they
passed by reference to the function that produced the array in session?
of so then you could be redefining the session data at the same time as
retrieving it or something completely crazy.
actually I think your php install is bustikated!
