Convert a PHP "Object" to a SESSION?

I have a {$obj->product_stock} which contains a numeric value - the stock of the product.

How can I convert that {$obj->product_stock} to a SESSION? Here is what I tried...

$_SESSION['product_stock'] = {$obj->product_stock};

Why does it error and how can I get round this?

<?php
    session_start();
    include_once("config.php");

    // Current URL of the Page. cart_update.php redirects back to this URL
    $current_url = urlencode($url="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
?>

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

<!-- Products List Start -->
<?php
$ProductID = intval($_REQUEST['ProductID']);
$results = $mysqli->query("SELECT * FROM products where ProductID = '$ProductID';");

if($results) {
    $_SESSION['product_stock'] = $obj->product_stock;
    echo "STOCK: ". $_SESSION['product_stock'] ."";

    $products_item = '<ul class="products">';
    // Fetch results, set as object and output HTML
    while($obj = $results->fetch_object()) {
        $products_item .= <<< EOT
        <li class="product">

Your code:

$_SESSION['product_stock'] = $obj->product_stock; echo "STOCK: ". $_SESSION['product_stock'] ."";

is outside the while loop. Therefore $obj is not yet defined.

Move the code above into the while loop like this

$products_item = '<ul class="products">';
// Fetch results, set as object and output HTML
while($obj = $results->fetch_object()) {
    $_SESSION['product_stock'] = $obj->product_stock;
    echo "STOCK: ". $_SESSION['product_stock'] ."";
    ....
