Question

我想根据给定的信息从PHP数组中提取信息。

Php是

$xmlstring = file_get_contents('http://www.bookingassist.ro/XML/test.xml');
$xml = simplexml_load_string($xmlstring);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
$HotelCodes[] = array('BG01I9', 'BG53I4', 'BG23I7');
$code = $HotelCodes[1];
if (!$code) {
   throw new Exception("No Hotel Code specified");
}
foreach ($HotelCodes as $code) {
  foreach ($hotels as $hotel) {
    if (strcasecmp($hotel['HotelCode'], $code) === 0) {
        echo "{$hotel['Latitude']}:{$hotel['Longitude']}<br/>";
        foreach ($hotel['HotelImages']['ImageUrl'] as $img) {
            echo "<img src='{$img}'/><hr/>";
        }
        break;
    }
  }
}

带有一条记录的

print_r $array（数组有多条记录）：

Array
( 
    [Hotel] => Array 
  ( 
[0] => Array ( 
     [HotelCode] => BG01I9 
     [Latitude] => 42.6039 
     [Longitude] => 23.3954 
     [HotelImages] => Array ( 
           [ImageURL] => Array ( 
                        [0] => http://image.metglobal.com/hotelimages/BG01I9/6481077_0x0.jpg 
                        [1] => http://image.metglobal.com/hotelimages/BG01I9/6481092_0x0.jpg 
                        [2] => http://image.metglobal.com/hotelimages/BG01I9/6481109_0x0.jpg 
                        [3] => http://image.metglobal.com/hotelimages/BG01I9/6481139_0x0.jpg

我希望根据我提供的HotelCodes回应酒店图片，纬度和经度：酒店代码为$HotelCodes[0]

收到的错误是：

Fatal error: Uncaught exception 'Exception' with message 'No Hotel Code specified' in /home/truckass/public_html/site/test/teste.php:10 Stack trace: #0 {main} thrown in /home/truckass/public_html/siteo/test/teste.php on line 10

我需要回复HotelCodes[1]

$img[1][0] ....$img[1][5] 
$Latitude[1]
$Longitude[1]

请你帮忙。

循环数组并检查HotelCode是否与指定匹配：

$HotelCodes = array('BG01I9', 'BG53I4', 'BG23I7');

if (!$code) {
   throw new Exception("No Hotel Code specified");
}

foreach ($HotelCodes as $code) {
  foreach ($hotels as $hotel) {
    if (strcasecmp($hotel['HotelCode'], $code) === 0) {
        echo "{$hotel['Latitude']}:{$hotel['Longitude']}<br/>";

        foreach ($hotel['HotelImages']['ImageUrl'] as $img) {
            echo "<img src='{$img}'/><hr/>";
        }

        break;
    }
  }
}
