Question

我想删除所有键 [Name] ，但主要问题是列表键中的数字（[List1]，[List2]等）。键[List]上的数字可能更多，但例如我只给了两个。

我想改变它，因为它是一个旧的json文件，而在新版本中它没有密钥，比如转换器

有没有办法遍历整个阵列并删除所有[名称]键？

Array(
 [Values] => 1
 [List1] => Array(
    [Product1] => Array( 
       [0] => Array(
          [Properties] => Array( 
            [Id] => 1
            [Name] => Nm1
          )
        )
        [1]=> Array(
            [Properties] => Array(  
                [Id] => 1
                [Name] => Nm1
            )
        )
    )
    [List1] => Array(
        [Product1] => Array( 
            [0] => Array(
                [Properties] => Array( 
                    [Id] => 1
                    [Name] => Nm1
                )
            )
        )
    )
    [List2] => Array(
        [Product1] => Array( 
            [0] => Array(
                [Properties] => Array( 
                    [Id] => 1
                    [Name] => 0
                )
            )
        )
    )
  )
  [List2] => Array(
    [Product1] => Array( 
        [0] => Array(
            [Properties] => Array( 
                [Id] => 1
                [Name] => Nm1
            )
        )
    )
    [List1] => Array(
        [Product1] => Array( 
            [0] => Array(
                [Properties] => Array( 
                    [Id] => 1
                    [Name] => Nm1
                )
            )
        )
    )
 )
)

我的目标是：

Array(
 [Values] => 1
 [List1] => Array(
    [Product1] => Array( 
       [0] => Array(
          [Properties] => Array( 
            [Id] => 1
          )
        )
        [1]=> Array(
            [Properties] => Array(  
                [Id] => 1
            )
        )
    )
    [List1] => Array(
        [Product1] => Array( 
            [0] => Array(
                [Properties] => Array( 
                    [Id] => 1
                )
            )
        )
    )
    [List2] => Array(
        [Product1] => Array( 
            [0] => Array(
                [Properties] => Array( 
                    [Id] => 1
                )
            )
        )
    )
  )
  [List2] => Array(
    [Product1] => Array( 
        [0] => Array(
            [Properties] => Array( 
                [Id] => 1
            )
        )
    )
    [List1] => Array(
        [Product1] => Array( 
            [0] => Array(
                [Properties] => Array( 
                    [Id] => 1
                )
            )
        )
    )
 )
)

我试过了：

$ProductCount= count($array['List1']['Product1']);
for($i = 0;$i<$ProductCount;$i++){
  unset($array['List1']['Product1'][$i][Properties][Name]);
}

但我也有一个键[List2]，可以是[List3]等。

你可以这样做：

function remove_key($array, $key)
{
    foreach($array as $k => $v) {
    if(is_array($v)) {
        $array[$k] = remove_key($v, $key);
    } elseif($k == $key) {
        unset($array[$k]);
    }
    }
    return $array;
}

$array = remove_key($array, 'Name');

$array是您的多维数组，$key是您要删除的键名。注意：如果键表示一个数组（不是值），此方法将忽略它，但我认为这是您需要的。如果要在密钥匹配时删除数组，则需要在foreach循环中切换条件顺序。

在多维数组PHP中重新清除所有特定键
