How can I list the values & make variable with the values of this json? (In PHP)

So I have tried that:

$json = json_decode($response, true); echo $json['link'];

but I didn’t get anything as output.

I have this json object:

So how can I get & list the values of these? I will be very happy if someone can help me with this. I’m begginer with json values :/

Answer

You are returning an array of arrays. You need to access them using an index

$json["results"][0]['link']
