Question

我有一个雄辩的对象，该对象包含来自模型的数据，我需要将其转换为数组，并具有来自关系的所有索引，并且它们位于同一数组深度。

我尝试了array_flatten(), map(), filter()和其他PHP方法，但无法使其正常工作。

我如何建立关系：

    $data = Person::whereIn('id', $this->id[0])->where('school_id', '=', 
    $this->school)->with(['personinfo'=>function ($query) {
        $query->select(
            'person_id',
            'general_info',
        );
    }, 'trades'=>function ($query) {
        $query->select('person_id', 'trade_id')->with('trades');
    }, 'measurements'=>function ($query) {
        $query->select(
            'person_id',
            'measuring_point_1',
            'measuring_point_1_date',
        );
    }])->get();

    return $data->toArray();

下面数组中的结果是什么，这与我使用不同方法所获得的结果非常接近。

这是返回函数的结果：

array:3 [
  1 => array:17 [
    "school_id" => 6
    "birth_date" => null
    "sex_id" => 1
    "phone_number" => 62452676867897
    "mobile_number" => 62398356786787
    "email" => "example@example.com"
    "personinfo" => array:5 [
      "person_id" => 21
      "general_info" => null
      "health_info" => null
    ]
    "trades" => array:3 [
      "person_id" => 21
      "trade_id" => 2
      "trades" => array:8 [
        "school_id" => 2
        "name" => "blablabla"
      ]
    ]
    "measurements" => array:7 [
      "person_id" => 21
      "measuring_point_1" => null
      "measuring_point_1_date" => null
    ]
  ]
];

我需要这样的数组：

array:3 [
  1 => array:17 [
    "school_id" => 6
    "birth_date" => null
    "sex_id" => 1
    "phone_number" => 624176676867897
    "mobile_number" => 649498356786787
    "email" => "example@example.com"
    "person_id" => 21
    "general_info" => null
    "health_info" => null
    "person_id" => 21
    "trade_id" => 2
    "school_id" => 2
    "name" => "blablabla"
    "person_id" => 21
    "measuring_point_1" => null
    "measuring_point_1_date" => null
    ]
  ]
];

基本上，我需要将多维数组转换为零深度数组。

任何帮助将不胜感激。

Answer 1

您可以使用数组展平的自定义，将内部与array-merge合并为：

function arrayFlatten($array) {
   $res = array();
   foreach ($array as $k => $v) {
       if (is_array($v)) $return = array_merge($res, array_flatten($v)); // add recursively
       else $res[$k] = $v; // just add
   }
   return $res;
}

现在只需返回arrayFlatten($data->toArray());

简单的live example

我如何使用dWinder的答案进行工作

       $data = Person::whereIn('id', $this->id[0])->where('school_id', '=', $this->school)->with(['personinfo'=>function ($query) {
        $query->select(
            'person_id',
            'general_info',
        );
    }, 'trades'=>function ($query) {
        $query->select('person_id', 'trade_id')->with('trades');
    }, 'measurements'=>function ($query) {
        $query->select(
            'person_id',
            'measuring_point_1',
            'measuring_point_1_date',
        );
    }])->get();


function array_flatten($array)
    {
        $return = array();
        foreach ($array as $key => $value) {
            if (is_array($value)) {
                $return = array_merge($return, array_flatten($value));
            } else {
                $return[$key] = $value;
            }
        }
        return $return;
    }

    foreach ($data as $value) {
        $result[] = array_flatten($value->toArray());
    }


    return $result;

如何将雄辩的对象转换为零深度数组？
