将新值保存到Laravel会话数组

Question

I have the following code where I loop through the items in the session array and change the value. How can I save it back to the session?

foreach(Session::get('cart.program') as &$item) {
    if ($item['id'] == '1xxx') { 
        item['id'] = '2xxx';
        break;
    }
}

Answer 1

One way of doing it

$cart = Session::get('cart.program');

foreach($cart as &$item) {
    if ($item['id'] == '1xx') { 
        $item['id'] = '2xx';
        break;
    }
}

Session::put('cart.program', $cart);

Answer 2

Use Session::put() to save to the session in Laravel:

foreach(Session::get('cart.program') as $item){
    if ($item['id'] == '1xxx') { 
        Session::put('cart.program.id', '2xxx');
        break;
    }
}
