Question

So I have in-app-billing working with PHP server verify. However, I cant figure out how to separate my signed data Strings into separate strings in PHP. When I echo $signedData in PHP I get the following.

{\"nonce\":4658477652655443541,\"orders\":[{\"notificationId\":\"android.test.purchased\",\"orderId\":\"transactionId.android.test.purchased\",\"packageName\":\"com.coolboy.coolapp\",\"productId\":\"android.test.purchased\",\"purchaseTime\":1350913071409,\"purchaseState\":0}]}

How do you separate the nonce, orders, and etc. in PHP to separate variables?

Thanks

Answer 1

Use json_decode to decode the string into an object.

This code:

$str = "{\"nonce\":4658477652655443541,\"orders\":[{\"notificationId\":\"android.test.purchased\",\"orderId\":\"transactionId.android.test.purchased\",\"packageName\":\"com.coolboy.coolapp\",\"productId\":\"android.test.purchased\",\"purchaseTime\":1350913071409,\"purchaseState\":0}]}";
$json = json_decode($str);
var_dump($json);

Produces:

class stdClass#1 (2) {
  public $nonce =>
  double(4.6584776526554E+18)
  public $orders =>
  array(1) {
    [0] =>
    class stdClass#2 (6) {
      public $notificationId =>
      string(22) "android.test.purchased"
      public $orderId =>
      string(36) "transactionId.android.test.purchased"
      public $packageName =>
      string(19) "com.coolboy.coolapp"
      public $productId =>
      string(22) "android.test.purchased"
      public $purchaseTime =>
      double(1350913071409)
      public $purchaseState =>
      int(0)
    }
  }
}

And of course you can do:

$nonce = $json->nonce;
$notificationId = $json->orders[0]->notificationId;
// etc...
