Re: [PHP] SESSION array problems

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.

hi tedd,

if I may suggest this "model"

$_SESSION
{
[6156]
{
[first_name] => Diane
[last_name] => Cable
}

[7030]
{
[first_name] => Fred
[last_name] => Cago
}

[656]
{
[first_name] => Helen
[last_name] => Cahalan
}
}
main reason - if you sort by first or last name you will lose "index".
this way is index always "linked" to first/last name.

foreach ($_SESSION as $key => $value)
{
echo $_SESSION[$key]['last_name'].',
'.$_SESSION[$key]['first_name'].'<br>';
}

didn't test it, though :-)
