このjsonストリングのデコードに問題があります

Question

こんにちは私はこのjsonストリングのデコードに問題があります。 入力の[アドレス]タブにデータが必要です。 私はこれをはるかに上回っていますが、うまく動かないようです。 彼はインデックスを見つけることができないと言います：prev_out。

$obj = json_decode($json, true); 
print_r($obj['inputs']['prev_out']['addr']); 

ありがとうございます！ JSONは以下の通りです： - あなたはまだ持っていない場合

Answer 1

要素prev_outは、別の要素の内部にネストされています。これにアクセスする：

print_r($obj['inputs'][0]['prev_out']['addr']); 

Answer 2

、その後、実際のjson structureに応じてクラスを作成し、それらにそれをデシリアライズ。あなたがこのフォーマットを尊重するなら、それはうまくいくでしょう。
