unserialize -- need help

zzz

I have an array that contains some user data. Now I'd like to add some logic based on the role, but am unable to get the value. I've tried the following way:

session_start();

$a = unserialize($_SESSION['user']['data']['role']);

foreach ($a as $b) {
   echo $b;
}

When I just print $_SESSION['user']['data']['role'] I get Array()

It seems "unserialize" doesn't want to work in this case...

What am I doing wrong?

where did you set the $_SESSION? it seem the session is empty.

😕 I'm not sure this is _SESSION issue.

I am able to get the rest of the vars via session...

Also I get an Array() echoed...

is there any specific reason you are serializing the data in the first place since it is stored in a session? serialization is useful for preserving data in files or a database to recall at a later time, but the session is already saving the data for you.

It is a third-party software and yes, they store it in the db. This is the only way I can get data.

if it is showing Array when you run the foreach, try to print_r the variable to see what it is.

... still get Array()...

print_r($var) should show the contents of the array if there is anything in it. if all you see from doing it is Array() then it means it is an empty array.
