PHPを使って多次元配列で値を取得

Question

多次元配列から配列の値を取得したいと思います。私はPHPのjson_decode（）関数を使ってデコードしたAPIからのjson応答を持っていて、データを反復するためにループを使いたいとしましょう。

$string = $response; 
$json_a = json_decode($string, true); 


foreach($json_a['withdrawals'] as $item) { 

    echo $item['withdrawalId']['amount']['currencyCode']. '<br/>'; 
    echo $item['withdrawalId']['terminal']['tid']. '<br/>'; 
    echo $item['withdrawalId']['user']['mid']. '<br/>'; 
    echo $item['servicefee']['masterMerchant']['name']. '<br/>'; 
    echo $item['servicefee']['masterMerchant']['address']['address1']. '<br/>'; 
    } 
} 

print_r($json_a); 

ここには配列のプリントアウトがあります。

    "acceptedTotalTransactionsCount": 4428,

          } 
        } 
       } 
     } 
     }]}

はこのようにそれを書く： - だから、

$string = $response; 
$json_a = json_decode($string, true); 


    foreach($json_a['withdrawals'] as $item) { 
     echo $item['withdrawalId']. '<br/>'; 

     echo $item['amount']['currencyCode']. '<br/>'; 
     echo $item['terminal']['tid']. '<br/>'; 
     echo $item['user']['mid']. '<br/>'; 
     echo $item['user']['masterMerchant']['name']. '<br/>'; 
     echo $item['user']['masterMerchant']['address']['address1']. '<br/>'; 
     } 
    } 

    print_r($json_a);
