How to send 2 arrays/parameters through the url?

Question

I am trying to send two parameters of the shopping cart through the url ,for later the client to make the confirmation, but I can only receive an array on the other page and do not know how to receive two.

I want to send the quantity of products and the id_products to another page, where the user will confirm and then enter database.

On the cart page

<?php
**// array para guardar todos os valores que estão no carrinho
$emparray[] = $product['id_produto'];
$quant[] = $product['quantidade'];
...

// transformar a array numa associação de parâmetros para a url
$query = http_build_query($emparray);
testar = http_build_query($quant);

$cart_box .= '<div class="cart-products-total">Total : '.$total.' € <u><a href="index.php?page=confirmar_encomenda&'.$query.'&'.$testar.'"  title="Verifica o carrinho e faz checkout">Concluir</a></u></div>';

?>

On the other page, this is how I receive the values. In order to send in the form confirmation.

<?php
$teste=$_GET;
echo $teste;

foreach($teste as $value){
   echo' <input type='text" name="result[]" value="'. $value.'">';
}
?>

But this way he only shows the last array and I’ve tried N ways to receive the two separately but could not.

Two things:

1. Avoid passing this type of purchase data by GET, use the method POST. Besides being safer, there’s a limit on the amount of characters you can pass through GET 2083 characters. It seems a lot, but if your customer is buying 100 different products it may well exceed this limit.

2. When you define the arrays that will go through http_build_query you are passing the value directly, so the resulting array should be arrays with numbered rather than associative indices, so the GET must be overwriting the parameters you are passing to it, i.e.: the result in the URL must be more than one parameter with the same key: ?page=confirmar_encomenda&0=1344&0=2. Instead of using two arrays, why not pass the products array that contains all the information?

$query = http_build_query($product);
