我在 PHP 工作。

我有以下包含关系数据(父子关系)的数组。

Array        
(        
    [5273] => Array        
        (        
            [id] => 5273        
            [name] => John Doe        
            [parent] =>         
        )        

    [6032] => Array        
        (        
            [id] => 6032        
            [name] => Sally Smith        
            [parent] => 5273        
        )        

    [6034] => Array        
        (        
            [id] => 6034        
            [name] => Mike Jones        
            [parent] => 6032        
        )        

    [6035] => Array        
        (        
            [id] => 6035        
            [name] => Jason Williams        
            [parent] => 6034        
        )        

    [6036] => Array        
        (        
            [id] => 6036        
            [name] => Sara Johnson        
            [parent] => 5273        
        )        

    [6037] => Array        
        (        
            [id] => 6037        
            [name] => Dave Wilson        
            [parent] => 5273        
        )        

    [6038] => Array        
        (        
            [id] => 6038        
            [name] => Amy Martin        
            [parent] => 6037        
        )        
)        

我需要它采用这种 JSON 格式:

{        
   "id":"5273",        
   "name":"John Doe",        
   "data":{        

   },        
   "children":[        
      {        
         "id":" Sally Smith",        
         "name":"6032",        
         "data":{        

         },        
         "children":[        
            {        
               "id":"6034",        
               "name":"Mike Jones",        
               "data":{        

               },        
               "children":[        
                  {        
                     "id":"6035",        
                     "name":"Jason Williams",        
                     "data":{        

                     },        
                     "children":[        
                        {        
                           "id":"node46",        
                           "name":"4.6",        
                           "data":{        

                           },        
                           "children":[        

                           ]        
                        }        
                     ]        
                  }        
               ]        
            },        
            {        
               "id":"6036",        
               "name":"Sara Johnson",        
               "data":{        

               },        
               "children":[        

               ]        
            },        
            {        
               "id":"6037",        
               "name":"Dave Wilson",        
               "data":{        

               },        
               "children":[        
                  {        
                     "id":"6038",        
                     "name":"Amy Martin",        
                     "data":{        

                     },        
                     "children":[        

                     ]        
                  }        
               ]        
            }        
         ]        
      }        
   ]        
}        

我知道我需要创建一个多维数组并通过 json_encode() 运行它。我还相信用于执行此操作的这种方法需要递归，因为现实世界的数据可能具有未知数量的级别。

我很乐意展示我的一些方法，但它们没有奏效。

谁能帮帮我？

我被要求分享我的工作。这是我尝试过的方法，但我还没有那么接近我不知道它有多大帮助。

我只制作了一个关系数组。

foreach($array as $k => $v){
    $relationships[$v['id']] = $v['parent'];
}

我认为(基于另一个 SO 帖子)使用此关系数据创建了一个新的多维数组。如果我让它工作，我将努力添加正确的“ child ”标签等。

$childrenTable = array();
    $data = array();
    foreach ($relationships as $n => $p) {
      //parent was not seen before, put on root
      if (!array_key_exists($p, $childrenTable)) {
          $childrenTable[$p] = array();
          $data[$p] = &$childrenTable[$p];  
      }
      //child was not seen before
      if (!array_key_exists($n, $childrenTable)) {
          $childrenTable[$n] = array();
      }
      //root node has a parent after all, relocate
      if (array_key_exists($n, $data)) {
          unset($data[$n]);
      }
      $childrenTable[$p][$n] = &$childrenTable[$n];      
    }
    unset($childrenTable);

print_r($data);
