Set PHP variable to value in JSON object - php

Question

I have a PHP file which gets a JSON object called $response. The $response has many values (as shown below) and I want to extract a few includes title and price. I have tried the below code but it doesnt show ANY result (no error, no value!). Thoughts?
Thank you
PHP code:
$data = json_decode($response, true);
echo $data->ItemsResult->Items[0]->ItemInfo->Title->DisplayValue;
$response =
{

The second argument of json_decode function enables associative array result. So in your case you can either do
$data = json_decode($response);
echo $data->ItemsResult->Items[0]->ItemInfo->Title->DisplayValue;
or
$data = json_decode($response, true);
echo $data['ItemsResult']['Items'][0]['ItemInfo']['Title']['DisplayValue'];
