阵列和子集

我有以下的数组：

阵列（[@属性] =>数组（[版] => 010 [发布] => 006） [页眉] = > Array（[To] => 6891118750001 [From] => 9911557 [MessageID] => 306b197fff044421b31c0a2a15e356c1 [RelatesToMessageID] =>分辨率[SentTime] => 2014-09-16T12：19：50.8Z [Security] => Array （[发送方] =>数组（[第135] ] => Array（ [Refil阵列（[Identification]] => 阵列（[NCPDPID] => 9911557 [NPI] => 1801849179）[StoreName] =>药房10.6MU [地址] =>阵列（[AddressLine1] => 65432 Cabernet Turn [City] => Sonoma [State] => CA [ZipCode] => 95476） [CommunicationNumbers] => Array（[Communication] => Array（[Number] =>数组（[数据库] =>数组（[NPI] => 1234567893）[Name] =>数组（ [LastName] => Jefferson）[Address] => > Array（[AddressLine1] => 5555 Labelle Lane [City] => Gaithersburg [State] => MD [ZipCode] => 20877） [CommunicationNumbers] => Array（[Communication] => Array（[0] = > Array（[Number] => 3105551515 [Qualifier] = >数组（ [Name] =>数组（[LastName] => Li [FirstName> TE）[1] => Array（ [Number] => 3015551516 [Qualifier] => FX））） ] => Ci）[性别] => U [DateOfBirth] =>阵列（[Date] => 1923-10-18）） [MedicationPrescribed] => Array（[DrugDescription] => ZIOPTAN 0.0015％ 眼用溶液[CodeCode] => Array [（ProductCode] => 00006393130 [ProductCodeQualifier] => ND）[Quantity] => Array（ [Value] => 1 [CodeListQualifier] => 38 [UnitSourceCode] => AC [PotencyUnitCode ] => C54702）[Directions => D [Substitutions] => 0 [WrittenDate] => Array（[Date] => 2014-04-01）） [MedicationDispensed] => Array（[DrugDescription] => ZIOPTAN 0.0015％ Ophthalmic Solution [DrugCoded] => Array（[ProductCode] => 00006393130 [ProductCodeQualifier] => ND [DrugDBCode] => 1244616 [DrugDBCodeQualifier] => SBD）[Quantity] => Array（[Value] => 1 [CodeListQualifier] => 38 [UnitSourceCode] => AC [PotencyUnitCode] => C54702）[Directions] => D [Substitutions] => 0 [WrittenDate] => Array （[Date] => 01）[LastFillDate] =>数组（[日期] => 2014年4月2日）））））版本= 010

但是当我循环通过它与此代码：

function displayArrayRecursively($arr, $indent='') { 
    if ($arr) { 
     foreach ($arr as $value) { 

      if (is_array($value)) { 

       displayArrayRecursively($value, $indent . ''); 
      } else { 
       echo key($arr) . " = $value<br>"; 
      } 
     } 
    } 
} 

displayArrayRecursively($arrXml); 

它会打印所有的值，但并不是所有正确的子集键名都关联。有任何想法吗？

谢谢！

不要使用key()功能但foreach()直接与变量$key（或其他名称）访问阵列的关键。此外，你甚至没有使用变量$indent，所以我添加了你需要的一段代码。 这是你正在寻找的功能：

function displayArrayRecursively($arr, $indent='') 
{ 
    if ($arr) 
     foreach ($arr as $key => $value) 
      if (is_array($value)) 
       displayArrayRecursively($value, $indent.'--'); 
      else 
       echo $indent.$key." = $value<br>"; 
}
