foreach($_SESSION AS $value){...} -> get array key of session

Question

I fill a session like this:

$_SESSION[$id]=$value;

And I'm reading out the array with this:

foreach($_SESSION AS $value){...}

But how can I read out the $id of the session too? Array key?

Thanks!

foreach($_SESSION as $key => $value){

You need something like the following:

foreach($_SESSION AS $key => $value) {
  echo "$key -> $value";
}
