創建數組嵌套的PHP

Question

大家好我有一個頁面到PHP，我從服務器檢索XML數據，我想將這些數據存儲到一個數組中。

這是我的代碼：

foreach ($xml->DATA as $entry){ 
    foreach ($entry->HOTEL_DATA as $entry2){ 
     $id = (string)$entry2->attributes()->HOTEL_CODE; 
     $hotel_array2 = array(); 
     $hotel_array2['id'] = $entry2->ID; 
      $hotel_array2['name'] = utf8_decode($entry2->HOTEL_NAME); 
     $i=0; 
     foreach($entry2->ROOM_DATA as $room){ 
      $room_array = array(); 
      $room_array['id'] = (string)$room->attributes()->CCHARGES_CODE; 
      $hotel_array2['rooms'][$i] = array($room_array); 

      $i++; 
     } 
      array_push($hotel_array, $hotel_array2); 
     } 
} 

在這種模式下我有數組hotel_array所有酒店客房帶。 問題是：在我的XML中，我可以擁有多個具有相同ID（相同酒店）的酒店，但信息相同但房間不同。 如果我有一個酒店，我已經插入到我的hotel_array我不想插入一個新的數組，但我只想把它的房間陣列，並插入到現有的酒店。 實例現在我的情況是：

hotel_array{ 
     [0]{ 
      id = 1, 
      name = 'test' 
      rooms{ 
       id = 1 
      } 
     } 
     [0]{ 
      id = 2, 
      name = 'test2' 
      rooms{ 
       id = 100 
      } 
     } 
     [0]{ 
      id = 1, 
      name = 'test' 
      rooms{ 
       id = 30 
      } 
     } 
} 

我想有這樣的結果，而不是：

hotel_array{ 
     [0]{ 
      id = 1, 
      name = 'test' 
      rooms{ 
       [0]{ 
        id = 1 
       } 
       [1]{ 
        id = 30 
       } 
      } 
     } 
     [0]{ 
      id = 2, 
      name = 'test2' 
      rooms{ 
       id = 100 
      } 
     } 
} 

如何創建一個這樣的數組？

感謝

第一件事就是它有助於保持酒店id作爲指數hotel_array當你創建它。

foreach ($xml->DATA as $entry){ 
    foreach ($entry->HOTEL_DATA as $entry2){ 
     $id = (string)$entry2->attributes()->HOTEL_CODE; 
     $hotel_array2 = array(); 
     $hotel_array2['id'] = $entry2->ID; 
      $hotel_array2['name'] = utf8_decode($entry2->HOTEL_NAME); 
     $i=0; 
     foreach($entry2->ROOM_DATA as $room){ 
      $room_array = array(); 
      $room_array['id'] = (string)$room->attributes()->CCHARGES_CODE; 
      $hotel_array2['rooms'][$i] = array($room_array); 

      $i++; 
     } 
      if (!isset($hotel_array[$hotel_array2['id']])) { 
        $hotel_array[$hotel_array2['id']] = $hotel_array2; 
      } else { 
        $hotel_array[$hotel_array2['id']]['rooms'] = array_merge($hotel_array[$hotel_array2['id']]['rooms'], $hotel_array2['rooms']); 
      } 
     } 
}

雖然這是類似的答案DevZer0（+1），也有相當多的可以做，以簡化您的工作方式......有沒有必要使用array_merge爲一體，或者是特定的約在您的房間陣列中的$i。

$hotels = array(); 
foreach ($xml->DATA as $entry){ 
    foreach ($entry->HOTEL_DATA as $entry2){ 
    $id = (string) $entry2->attributes()->HOTEL_CODE; 
    if (empty($hotels[$id])) { 
     $hotels[$id] = array(
     'id' => $id, 
     'name' => utf8_decode($entry2->HOTEL_NAME), 
     'rooms' => array(), 
    ); 
    } 
    foreach($entry2->ROOM_DATA as $room){ 
     $hotels[$id]['rooms'][] = array(
     'id' => (string) $room->attributes()->CCHARGES_CODE; 
    ); 
    } 
    } 
} 

萬一它可以幫助...

這:)

$hotel_array = array(); 

foreach ($xml->DATA as $entry) 
{ 
    foreach ($entry->HOTEL_DATA as $entry2) 
    { 
     $hotel_code = (string) $entry2->attributes()->HOTEL_CODE; 

     if (false === isset($hotel_array[$hotel_code])) 
     { 
      $hotel = array(
       'id' => $entry2->ID, 
       'code' => $hotel_code, 
       'name' => utf8_decode($entry2->HOTEL_NAME) 
      ); 

      foreach($entry2->ROOM_DATA as $room) 
      { 
       $hotel['rooms'][] = array(
        'id' => (string)$room->attributes()->CCHARGES_CODE, 
       ); 
      } 

      $hotel_array[$hotel_code] = $hotel; 
     } 
    } 
}
