がキー

Question

に基づいてPHPアレイ1のレベルを平らにし、私は現在、次のように出力されます配列を持っている：私がする必要がどのような

             [postal_code] => 53103 
             [country] => USA 
            ) 
           ) 
          ) 
         ) 
         [collaborators_list] => 
         [1] => Array 
         (
          [account] => Array 
          (
           [id] => 1 
           [account_name] => Brand New 
          ) 
         ) 
        ) 
       ) 
      ) 
     ) 
    ) 
) 

は基本的にはintでキーがあるレベルを削除しています。したがって、例えば[total_events]は[events_list]と同じレベルにあり、その間には[0]がありません。 [<int>]キーがある他の領域についても同様です。

私はPHPを使用していますが、それを平坦化するためにさまざまな試みを試みましたが、そこにはかなり到達できませんでした。

ありがとうございます！

Answer 1

function flattenByRemoveingIntKeys($array) 
{ 
    foreach ($array as $key => $val) 
    { 
     if (is_array($val)) 
      $array[$key] = flattenByRemoveingIntKeys($val); 
     else if (is_numeric($key)) 
     { 
      $array .= $val[$key]; 
      unset($array[$key]); 
     } 
    } 
} 

実際にはテストされていませんが、そのようなものはうまくいくはずです。

Answer 2

これを試してみてください：

function RemoverIntKeys($array) { 
    foreach($array as $key => $value) { 
     if(preg_match("/^\d+$/",$key)) { 
     unset($array[$key]); 
     } 
    } 
      return $array; 
} 

$array = array("foo" => "baa", 2 => "hehe", "test" => "..", 4 => "hello"); 
$newarray = RemoverIntKeys($array); 
echo "<pre>"; 
print_r($newarray); 

出力：

Array 
    (
     [foo] => baa 
     [test] => .. 
    )
