What you're trying to do is decode JSON. PHP has a built in function for this aptly named... json_decode. Assuming your JSON is a string ($json_string), here is how you would decode it:

$obj = json_decode($json_string);
$uname = $obj->auth->user->uname;

Or, if you prefer the array syntax, use the second argument in json_decode:

$arr = json_decode($json_string, true);
$uname = $obj['auth']['user']['uname'];
