Question

从数组关联创建复杂的对象PHP以获取信息酒店预订。在实践中，我必须从XML响应中恢复一些数据，我需要向最终用户显示这些数据。我会创建一个对象或东西来帮助我快速恢复数据。当您调用函数时，如上所述，您必须返回一个易于访问所有数据的对象，并且可以由市政当局进行迭代。 foreach＆gt;

$resXML = $test->sendXML($xml_req);
//$dom = new DOMDocument;
$dom = new DOMDocument('1.0');

$dom->loadXML($resXML);
$success = $dom->getElementsByTagName('success');
$error = $dom->getElementsByTagName('error');
$hotels = $dom->getElementsByTagName('hotel');
$room = $dom->getElementsByTagName('room');

$arr_hotels = [];
$arr_rooms = [];
$n_hotel=0;

foreach($hotels as $hotel){

    $idHotel = $hotel->getAttribute('xsd:id');
    $nomeHotel = $hotel->getAttribute('xsd:name');
    //echo "<strong>Nome Hotel: </strong>" . $hotel->getAttribute('xsd:name')."<br>";
    $arr_hotels[] = ['idHotel'=>$idHotel, 'nomeHotel'=>$nomeHotel];

    $rooms = $hotel->getElementsByTagName('room');

    foreach($rooms as $room){
        /*
        echo "Prezzo: " . $room->getAttribute('xsd:price')."<br>";
        $boardType = $room->getElementsByTagName('boardType');
        $roomType = $room->getElementsByTagName('roomType');
        echo "Nome Gruppo: " . $boardType[0]->getAttribute('xsd:groupName')."<br>";
        echo "Tipo Stanza: " . $roomType[0]->getAttribute('xsd1:nameEn')."<br>";
        */

        $boardType = $room->getElementsByTagName('boardType');
        $roomType = $room->getElementsByTagName('roomType');

        $idRoom = $room->getAttribute('xsd:id'); // Id della stanza
        $prezzo = $room->getAttribute('xsd:price'); // prezzo della stanza

        $idGruppo = $boardType[0]->getAttribute('xsd:groupId'); // Id Gruppo tipo di stanza
        $nomeGruppo = $boardType[0]->getAttribute('xsd:groupName'); // nome gruppo tipo stanza
        $idTipo = $boardType[0]->getAttribute('xsd1:id'); // Tipo specifico di stanza Colazione, Lunch
        $nomeTipo = $roomType[0]->getAttribute('xsd1:nameEn'); // nome del tipo

        $arr_hotels[]= array('idRoom'=>$idRoom,'prezzo'=>$prezzo);


    }

    $n_hotel++;
    return $arr_hotels;
}

如果我写这种类型的对象的方式不正确。有一个更简单的方法来经营一个有很多房间的酒店，然后可以通过简单的形式访问

$array_hotels[0]->name_hotel;

修改

我根据下面的答案制作了这些内容

function getHotelList(){
   foreach($hotels as $hotel){


   $h = new stdClass();

   $h->idHotel     = $hotel->getAttribute('xsd:id');
   $h->nomeHotel   = $hotel->getAttribute('xsd:name');
   $h->last_update = $hotel->getAttribute('xsd:lastUpdated');

   $rooms = $hotel->getElementsByTagName('room');




   //$idHotel = $hotel->getAttribute('xsd:id');
   //$nomeHotel = $hotel->getAttribute('xsd:name');
   //echo "<strong>Nome Hotel: </strong>" . $hotel->getAttribute('xsd:name')."<br>";
   //$arr_hotels[] = ['idHotel'=>$idHotel, 'nomeHotel'=>$nomeHotel];

   //$rooms = $hotel->getElementsByTagName('room');

   foreach($rooms as $room){
    /*
    echo "Prezzo: " . $room->getAttribute('xsd:price')."<br>";
    $boardType = $room->getElementsByTagName('boardType');
    $roomType = $room->getElementsByTagName('roomType');
    echo "Nome Gruppo: " . $boardType[0]->getAttribute('xsd:groupName')."<br>";
    echo "Tipo Stanza: " . $roomType[0]->getAttribute('xsd1:nameEn')."<br>";
    */

    $boardType = $room->getElementsByTagName('boardType');
    $roomType = $room->getElementsByTagName('roomType');


    $r = new stdClass();
    // Stanza
    $r->roomId          = $room->getAttribute('xsd:id'); // Id della stanza
    $r->prezzo          = $room->getAttribute('xsd:price'); // prezzo della stanza
    // Board Type
    $r->idGruppo        = $boardType[0]->getAttribute('xsd:groupId'); 
    $r->nomeGruppo      = $boardType[0]->getAttribute('xsd:groupName');
    $r->idTipoServizi   = $boardType[0]->getAttribute('xsd1:id');
    // Room Type
    $r->idRoomType      = $roomType[0]->getAttribute('xsd1:id'); 
    $r->nomeRoomType    = $roomType[0]->getAttribute('xsd:hotelstonName'); 

    $h->rooms[]     = $r;


    /*
    $idRoom = $room->getAttribute('xsd:id'); // Id della stanza
    $prezzo = $room->getAttribute('xsd:price'); // prezzo della stanza

    $idGruppo = $boardType[0]->getAttribute('xsd:groupId'); // Id Gruppo tipo di stanza
    $nomeGruppo = $boardType[0]->getAttribute('xsd:groupName'); // nome gruppo tipo stanza
    $idTipo = $boardType[0]->getAttribute('xsd1:id'); // Tipo specifico di stanza Colazione, Lunch
    $nomeTipo = $roomType[0]->getAttribute('xsd1:nameEn'); // nome del tipo

    $arr_rooms[$nomeHotel][]= array('idRoom'=>$idRoom,'prezzo'=>$prezzo);
    */

}

    $n_hotel++;
    $arr_hotels[] = $h;
}

$res = json_encode( $arr_hotels );
return $res;
}

好的。我不需要将函数getHotelList作为参数给出酒店名称... 我想返回一个变量/对象/数组，它将在下一个代码中为我提供服务。结果是到目前为止：

string(42910) "[{"idHotel":"50168124","nomeHotel":"Principe di Villafranca","last_update":"2016-09-18T23:29:02.927+03:00","rooms":[{"roomId":"11660402283","prezzo":"2788.59","idGruppo":"30309841","nomeGruppo":"Breakfast","idTipoServizi":"2359298","idRoomType":"70372446","nomeRoomType":"Superior Room - Double Bed"},{"roomId":"11660402283","prezzo":"2788.59","idGruppo":"30309841","nomeGruppo":"Breakfast","idTipoServizi":"2359298","idRoomType":"70372455","nomeRoomType":"Superior Room 2 Twin Beds"}]},{"idHotel":"50280829","nomeHotel":"Villa D'Amato","last_update":"2016-09-18T23:32:58.307+03:00","rooms":[{"roomId":"11660402116","prezzo":"127.14","idGruppo":"30309841","nomeGruppo":"Breakfast","idTipoServizi":"2359298","idRoomType":"70435376","nomeRoomType":"Standard Room Double - For Single Use, Double Bed"},{"roomId":"11660402118","prezzo":"137.74","idGruppo":"30309841","nomeGruppo":"Breakfast","idTipoServizi":"2359298","idRoomType":"70435429","nomeRoomType":"Superior Room Double - For Single Use, Double Bed"},{"roomId":"11660402287","prezzo":"147.60","idGruppo":"30309841","nomeGruppo":"Breakfast","idTipoServizi":"2359298","idRoomType":"52679712","nomeRoomType":"Standard Room"},{"roomId":"11660402121","prezzo":"148.34","idGruppo":"30309841","nomeGruppo":"Breakfast","idTipoServizi":"2359298","idRoomType":"70217317","nomeRoomType":"Standard Room Double Or Twin - Double Bed"},{"roomId":"11660402121","prezzo":"148.34","idGruppo":"30309841","nomeGruppo":"Breakfast","idTipoServizi":"2359298","idRoomType":"70217318","nomeRoomType":"Standard Room Double Or Twin"},{"roomId":"11661337064","prezzo":"151.39","idGruppo":"30309841","nomeGruppo":"Breakfast","idTipoServizi":"30309162","idRoomType":"65028065","nomeRoomType":"Standard Room Double Or Twin"},{"roomId":"11660402124","prezzo":"158.92","idGruppo":"30309841","nomeGruppo":"Breakfast","idTipoServizi":"2359298","idRoomType":"70217246","nomeRoomType":"Deluxe Room Double Or Twin - Double Bed"},etc..

到目前为止，这么好。但是如何访问数据呢？

  echo $res->nomeHotel;
  echo $res[0]->nomeHotel;
  echo $res[0]['nomeHotel'];

不能工作

Answer 1

我会这样做

$resXML = $test->sendXML($xml_req);
//$dom = new DOMDocument;
$dom = new DOMDocument('1.0');

$dom->loadXML($resXML);
$success = $dom->getElementsByTagName('success');
$error = $dom->getElementsByTagName('error');
$hotels = $dom->getElementsByTagName('hotel');
$room = $dom->getElementsByTagName('room');

$arr_hotels = [];
//$n_hotel=0; does not appear to be used

foreach($hotels as $hotel){
    $h = new stdClass();

    $h->idHotel     = $hotel->getAttribute('xsd:id');
    $h->nomeHotel   = $hotel->getAttribute('xsd:name');
    $h->last_update = $hotel->getAttribute('xsd:lastupdate');

    $rooms = $hotel->getElementsByTagName('room');

    foreach($rooms as $room){
        $r = new stdClass();

        $r->price       = $room->getAttribute('xsd:price');
        $r->boardType   = $room->getElementsByTagName('boardType');
        $r->roomType    = $room->getElementsByTagName('roomType');
        $r->groupname   = $boardType[0]->getAttribute('xsd:groupName');
        $r->nameEn      = $roomType[0]->getAttribute('xsd1:nameEn');
        $r->idRoom      = $room->getAttribute('xsd:id'); // Id della stanza
        $r->prezzo      = $room->getAttribute('xsd:price'); // prezzo della stanza
        $r->idGruppo    = $boardType[0]->getAttribute('xsd:groupId'); 
        $r->nomeGruppo  = $boardType[0]->getAttribute('xsd:groupName'); 
        $r->idTipo      = $boardType[0]->getAttribute('xsd1:id'); 
        $r->nomeTipo    = $roomType[0]->getAttribute('xsd1:nameEn'); 

        $h->rooms[]     = $r;
    }
    $arr_hotels[] = $h;

    //$n_hotel++;  Does not appear to be used
}
echo json_encode( $arr_hotels );

当然你可能需要检查你想要的属性名称，我假设lastupdate属性名称！

更新

根据你第一次尝试实现我的建议，现在你必须传递一个参数来使它全部启动。

function getHotelList($hotels){

    $arr_hotels[];

    foreach($hotels as $hotel){

        $h = new stdClass();

        $h->idHotel     = $hotel->getAttribute('xsd:id');
        $h->nomeHotel   = $hotel->getAttribute('xsd:name');
        $h->last_update = $hotel->getAttribute('xsd:lastUpdated');

        $rooms = $hotel->getElementsByTagName('room');

        foreach($rooms as $room){

            $boardType = $room->getElementsByTagName('boardType');
            $roomType = $room->getElementsByTagName('roomType');

            $r = new stdClass();
            $r->roomId      = $room->getAttribute('xsd:id');
            $r->prezzo      = $room->getAttribute('xsd:price'); 

            $r->idGruppo    = $boardType[0]->getAttribute('xsd:groupId'); 
            $r->nomeGruppo      = $boardType[0]->getAttribute('xsd:groupName');
            $r->idTipoServizi   = $boardType[0]->getAttribute('xsd1:id');

            $r->idRoomType      = $roomType[0]->getAttribute('xsd1:id'); 
            $r->nomeRoomType    = $roomType[0]->getAttribute('xsd:hotelstonName'); 

            $h->rooms[]     = $r;
        }
        $n_hotel++;
        $arr_hotels[] = $h;
    }
    return json_encode( $arr_hotels );
}


$resXML = $test->sendXML($xml_req);
$dom = new DOMDocument('1.0');

$dom->loadXML($resXML);
$success = $dom->getElementsByTagName('success');
$error = $dom->getElementsByTagName('error');
$hotels = $dom->getElementsByTagName('hotel');

$json_string = getHotelList($hotels);

UPDATE2

如果要访问PHP中的数据结构，那么就不要将其转换为JSON字符串，而是将其用作PHP数据结构

function getHotelList($hotels){

    $arr_hotels[];

    foreach($hotels as $hotel){

        $h = new stdClass();

        $h->idHotel     = $hotel->getAttribute('xsd:id');
        $h->nomeHotel   = $hotel->getAttribute('xsd:name');
        $h->last_update = $hotel->getAttribute('xsd:lastUpdated');

        $rooms = $hotel->getElementsByTagName('room');

        foreach($rooms as $room){

            $boardType = $room->getElementsByTagName('boardType');
            $roomType = $room->getElementsByTagName('roomType');

            $r = new stdClass();
            $r->roomId      = $room->getAttribute('xsd:id');
            $r->prezzo      = $room->getAttribute('xsd:price'); 

            $r->idGruppo    = $boardType[0]->getAttribute('xsd:groupId'); 
            $r->nomeGruppo      = $boardType[0]->getAttribute('xsd:groupName');
            $r->idTipoServizi   = $boardType[0]->getAttribute('xsd1:id');

            $r->idRoomType      = $roomType[0]->getAttribute('xsd1:id'); 
            $r->nomeRoomType    = $roomType[0]->getAttribute('xsd:hotelstonName'); 

            $h->rooms[]     = $r;
        }
        $n_hotel++;
        $arr_hotels[] = $h;
    }
    return $arr_hotels;
}


$resXML = $test->sendXML($xml_req);
$dom = new DOMDocument('1.0');

$dom->loadXML($resXML);
$success = $dom->getElementsByTagName('success');
$error = $dom->getElementsByTagName('error');
$hotels = $dom->getElementsByTagName('hotel');

$php_hotels = getHotelList($hotels);

// print_r($php_hotels);  // do this to see the data structure

foreach ( $php_hotels as $ph ) {
    echo $ph->nomeHotel;
}

要查看结构的外观，您需要做的只是print_r($php_hotels);
