如何在PHP中向变量添加foreach循环的结果

Question

foreach ($_SESSION["products"] as $cart_itm) {      
    $items = $cart_itm["code"]
    . " - " . $cart_itm["qty"]
    . " - "  . $cart_itm["price"]
    . "<br>" ;

    echo $items;
}

I have this code which gets every item from my basket and displays them, the problem is when I try to use this variable elsewhere in my code, it only displays the last item in the array, I realised that this is becasue the for loop keeps overwriting the last value . Is there a way I could put all results into one variable or use the loop to assign them too different variables maybe?

I also tried to put

foreach ($_SESSION["products"] as $cart_itm) {      
    $items .= $cart_itm["code"]
    . " - " . $cart_itm["qty"]
    . " - " . $cart_itm["price"]
    . "<br>" ;

    echo $items;
}

after looking through the forum but that returns me with items is not defined

so I tried to put

$items= ("") 

but still get the final result Any help is appreciated, thanks

$items = "";
foreach ($_SESSION["products"] as $cart_itm) {      
$items .= $cart_itm["code"] . " - " . $cart_itm["qty"] . " - "  . $cart_itm["price"] . "<br>" ;

}

echo $items;
