Question

    "multicast_id":8453676721258445896,
    "success":0,
    "failure":1,
    "canonical_ids":0,
    "results":[{
        "error":"InvalidRegistration"
    }]
}

我怎样才能在php中的一个变量中只获得成功和失败的值

Answer 1

$res ='{"multicast_id":8453676721258445896,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}';
$json_array=json_decode($res,true);

$success = $json_array["success"];
$failure = $json_array["failure"];
echo $success;
echo $failure;
