从关联数组创建复杂对象PHP

从数组中创建复杂对象PHP，用于酒店预订信息。

---

实际上，我必须从XML响应中恢复一些数据，这些数据需要显示给最终用户。 我会创建一个对象或其他东西来帮助我快速恢复数据。 当您调用一个函数时，比如上面的函数，您必须返回一个易于访问所有数据的对象，并且可以由

$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;
}

编辑 我根据下面的答案做了这些改动

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;
}

到目前为止，一切顺利。 但是我如何访问数据呢

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

不要工作

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，您可能需要检查属性名称是否符合您的要求，我假设

lastupdate

属性名称

更新 根据您第一次尝试实现我的建议，现在您必须向函数传递一个参数才能启动它

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);

更新2 如果您想访问PHP中的数据结构，那么不要将其转换为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，只需执行

print\r（$php\u hotels）
无效JSONIt甚至不是有效的PHP。这就像是无效JSON和PHP的混合@这太愚蠢了，我已经弄明白了！首先，向我们展示如何获取要构建到JSON数据结构中的数据。实际上，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其他东西来帮助我快速恢复数据。调用函数时，如上面的函数，必须返回一个易于访问所有数据的对象，并且可以通过创建JSON字符串的进行编辑，通常用于发送到页面上的某个javascript代码。如果你只使用PHP查看这些数据，你不需要这样做。谢谢@RiggsFolly，我现在就去试试
