How to grab JSON items from stdClass

Question

I'm using the Amazon API to pull info on products. I used this to pull the info:

$response = $amazonEcs->responseGroup('OfferFull')->lookup('B00IXO8I0O');
var_dump($response);

It outputs this (Warning -- long output, you can scroll to the bottom):

I can't figure out how to get the "FormattedPrice." (or any items for that matter)

How can I start pulling data out of that instead of the var_dump().

You can access StdClass properties like normal instance variables: $obj->param. For example, in this case we can access 'FormattedPrice' like this:

echo $response->Items->Item->OfferSummary->LowestNewPrice->FormattedPrice; // $299.99
