Try this one
<?php
session_start();
// create an array
$my_array=array('cat', 'dog', 'mouse', 'bird', 'crocodile', 'wombat', 'koala', 'kangaroo');
// put the array in a session variable
$_SESSION['animals']=$my_array;
// a little message to say we have done it
echo 'Putting array into a session variable';
// loop through the session array with foreach
foreach($_SESSION['animals'] as $key=>$value)
{
// and print out the values
echo 'The value of $_SESSION['."'".$key."'".'] is '."'".$value."'".' <br />';
}
?>
Your example I have given some value to the variable what ever you used
<?php
session_start();
$member = 'new';
$allFollowing = 'follower';
$getPoetry['poet'] = $_SESSION[$member]['filters']['newspaper'] = array('$in' => $allFollowing);
print_r($_SESSION[$member]['filters']['newspaper']);
print_r($getPoetry);
?>
@Yogesh Suthar case he missed key and 0 should not be in the sessions first key check that too
<?php
session_start();
$abcd = $_SESSION['test']['filters']['newspaper'] = array('test'=>"abcd");
print_r($_SESSION['test']['filters']['newspaper']);
print_r($abcd);
?>
