how to access 2nd array in an associative array - php

Question

I have an array returned from a json, I can access the values from one part of the array, but I can't access the values from another part of the array
echo '<strong>Barcode Number:</strong> ' . $response->products[0]->barcode_number . '<br><br>';
echo '<strong>Product Name:</strong> ' . $response->products[0]->product_name . '<br><br>';
echo '<strong>Description:</strong> ' . $response->products[0]->description . '<br><br>';
echo '<strong>Description:</strong> ' . $response->stores[0]->store_name . '<br><br>';
I get the first three fine but the last one for stores returns the error
Barcode Number: 077341125112
Product Name: Custom Accessories 89960W E-Tek Butane Torch
Description: Butane Torch, 89960W is ideal for your home garage or
your car. Can be used for quick repairs.

print_r($response);
echo '</pre>';
function get_data($url, $ch) {
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
Below is the array returned

Answer 1

When you format the data, it shows that the stores data is under each product, so you would need to display it as...
$response->products[0]->stores[0]->store_name
You would also probably need to use a foreach() to display all the details, both with products and the stores for each product.
foreach ( $response->products[0]->stores as $store ) {
// Echo out the details
echo $store->store_name;
}

Answer 2

Side-step: I think the easiest way to go about this process is using
json_decode($json, true);
This makes everything an associative array.
Here is the manual for the json_decode internal function.
Step-back:
$response->products[0]->stores[0]->store_name
