使用foreach进行复杂的多维数组处理

Question

我在尝试处理这个数组时遇到了问题尝试了几种不同的方法，但没有一种方法正确，这里是数组

Array ( 
  [search] => Array ( 
    [response] => Array ( 
      [errors] => 
      [number_of_hotels] => 1 of 1 
    ) 
    [lr_rates] => Array ( 
      [hotel] => Array  ( 
        [hotel_ref] => 3116 
        [hotel_currency] => [U] => USD 
        [hotel_rooms] => Array ( 
          [room] => Array ( 
            [ref] => 6382 
            [type] => 1 
            [type_description] => Standard 
            [sleeps] => 8 
            [rooms_available] => 
            [adults] => 8 
            [children] => 
            [breakfast] => false 
            [dinner] => false 
            [description] => 
            [alternate_description] => 
            [rack_rate] => 82.01 
            [date] => 19/08/201220/08/201221/08/2012
            [numeric_hotelcurrencyprice] => FullFullFull
            [formatted_date] => 19 August 201220 August 201221 August 2012 
            [price] => FullFullFull
            [hotelcurrencyprice] => FullFullFull 
            [numeric_price] => FullFullFull
            [requested_currency] => GBPGBPGBP 
            [numeric_hotelcurrencyprice] => FullFullFull
            [available_online] => false 
            [minimum_nights] => 1 
            [bed_type] => 
            [cancellation_policy] => 
            [cancellation_days] => 
            [cancellation_hours] => 
            [room_terms] => 
          )
          [room] => Array ( 
            [ref] => 6382 
            [type] => 1 
            [type_description] => Standard 
            [sleeps] => 8 
            [rooms_available] => 
            [adults] => 8 
            [children] => 
            [breakfast] => false 
            [dinner] => false 
            [description] => 
            [alternate_description] => 
            [rack_rate] => 82.01 
            [date] => 19/08/201220/08/201221/08/2012
            [numeric_hotelcurrencyprice] => FullFullFull
            [formatted_date] => 19 August 201220 August 201221 August 2012 
            [price] => FullFullFull
            [hotelcurrencyprice] => FullFullFull 
            [numeric_price] => FullFullFull
            [requested_currency] => GBPGBPGBP 
            [numeric_hotelcurrencyprice] => FullFullFull
            [available_online] => false 
            [minimum_nights] => 1 
            [bed_type] => 
            [cancellation_policy] => 
            [cancellation_days] => 
            [cancellation_hours] => 
            [room_terms] => 
          )
        ) 
        [cancellation_type] => First Night Stay Chargeable 
        [cancellation_policy] => 2 Days Prior to Arrival 

        [CityTax] => Array ( 
          [TypeName] => 
          [Value] => 
          [OptedIn] => 
          [IsCityTaxArea] => 
        )
      )
    )
  ) 
)

好吧我需要遍历数组并创建一个循环所以对于每个房间的实例它将重复该过程然后我需要从房间数组中提取数据并使用它来填充MySQL中的行会有多个房间实例这是我到目前为止的代码，它打印房间数组中的名称和值，但它只获得一个房间数组我可以做什么来设置它们全部读取，我也认为这太多了 - 每个但似乎无法遍历[''] [''] [''] ... 或者只使用关联名称。

foreach($arr['search'] as $lr_rates) {
        foreach($lr_rates['hotel'] as $hotel) {
                   foreach($hotel['room'] as  $field => $value){
                     print $field;print $value;
                          }

             }
      }

它也值得一提，这些数组中的值总是在波动

Answer 1

你不必在脚本中使用这么多的foreach循环，因为它看起来不太好。这是一个关联数组。 您只需使用其键即可访问关联数组。为它做一些谷歌。你可以找到很多脚本。

Answer 2

foreach($arr as $search) {
    foreach($search as $lr_rates) {
        foreach($lr_rates as $hotel) {
                 foreach($hotel as $hotel_rooms) {
                      print_r($hotel_rooms['room'])
                  }
            }
     }
}

编辑：这些许多foreach循环只是为了了解如何覆盖room。您也可以直接从课程中获得结果。

print_r($arr['search']['lr_rates']['hotel']['hotel_rooms']['room']);
