How to add new elements to a $_SESSION array in PHP

I am building a shopping cart and in my task I have to print out the items that the customer bought. I have tried to store the items in an array $_SESSION['items'] but no success. I have tried this:

$_SESSION['items'][] = $item;

but it did not work.

Please give some advice?

In my case, I was augmenting some existing base $_SESSION variable.

For example, I was initially just setting:

$_SESSION['amount'] = 4300

Then I tried to add a display 'sub-variable':

$_SESSION['amount']['Display'] = $4,300.00.

But I found that the second operation overwrote part of the base variable.

The fix was to do things explicitly:

$_SESSION['amount']['Amount'] = 4300;
$_SESSION['amount']['Display'] = $4,300.00

$_SESSION['req_id_in_sess'] = array();

$_SESSION['req_id_in_sess'] = $req_id; //$req_id is array 



 foreach($_SESSION["req_id_in_sess"] as $key => $val)
    { 

        echo $val,"<br/>";
    }

//for single output 

echo  $_SESSION["req_id_in_sess"][0];

for using session variables you have to start session using session_start(); to add elements try $_SESSION['items'][]=$items; and to print session variable try print_r($_SESSION['items'][]); or

foreach ($_SESSION['items'][] as $item)
{
       echo $item;
}

Did you use session_start()? You need to declare session_start() before you use $_SESSION in order to save values inside a session variable.

Also you are using a session array, so use print_r($_SESSION['items']) to see what it outputs, inorder to access the array value you need to specify the index too, for example

echo $_SESSION['items'][0]

use session_start(); to declare session. and use $_SESSION['items'][] = $item;

Should work..
