Help extracting data from JSON result

Question

I am having an issue retrieving the key from this JSON result returned from the last.fm api

this is what is being returned:

{"session":{"name":"mcbeav","key":"***************","subscriber":"1"}}

and i just need the key, but if i try to print_r or var_dump , nothing is displayed how would i go about doing so?

for example if i print_r($json['key']); or if i print_r['session']['key'];

what is printed is "{";

just use the php function

$myJsonData = json_decode($myJsonString,true)

it will give you an assocative array like you have in your code (what the second arguement true is for)

Hope that is what you are looking for

$json = json_decode('{"session":{"name":"mcbeav","key":"eab5a0axxxxxxx0c3","subscriber":"1"}}');
echo $json->session->key;

Or if you want an array:

$json = json_decode('{"session":{"name":"mcbeav","key":"eab5a0axxxxxxx0c3","subscriber":"1"}}', true);
echo $json['session']['key'];
