I’m attempting to pull in data from Google’s Shopping API. I’m able to download the data successfully, but I’m having trouble parsing through it with PHP. I’m still learning, but I seem to be having issues with multi-dimensional arrays. I capture the JSON with $json = json_decode($data);.
The following just echos the outer array, but I can’t pull from the inner array:
foreach($json as $key => $value) {
echo $key . " : " . $value;
}
If I want to grab the “title”, “description”, “brand”, and “availability” for each product, how would I parse through it?

Your JSON is a mix of arrays and objects. So array notation will not work for all items.
For example, to find the brand use:
