PHP: SOAP response sort results

本文关键字：排序结果响应 SOAP PHP | 更新日期: 2023-09-26

我正在尝试按soap响应的ROOMPRICE对结果进行排序:

stdClass Object ( 
    [GetHotelsResult] => stdClass Object ( 
        [SEARCH_RESPONSE] => Array ( 
            [0] => stdClass Object ( 
                [HOTELNAME] => Hotel1 
                [ROOMNAME] => Room2 
                [ROOMPRICE] => 144.50 
            ) 
            [1] => stdClass Object ( 
                [HOTELNAME] => Hotel1 
                [ROOMNAME] => Room1 
                [ROOMPRICE] => 231.10 
            ) 
            [2] => stdClass Object ( 
                [HOTELNAME] => Hotel1 
                [ROOMNAME] => Room3 
                [ROOMPRICE] => 94.00 
            ) 
        ) 
    ) 
);

我想出了很多解决办法，但都没用。

MY ACTUAL CODE:

$sClient = new SoapClient($wsdl, array('trace' => 1));
$response = $sClient->GetHotels($data);     
$ghdata = $sClient->__getLastResponse();
$doc = new DOMDocument();
$doc->loadXML($ghdata); 
$x = $doc->documentElement;
$rooms = $x->getElementsByTagName( "SEARCH_RESPONSE" );
    foreach( $rooms as $SEARCH_RESPONSE )
{ // show results

假设$response是您的外部stdClass对象，我想你会得到这样的错误:

Warning: usort() expects parameter 1 to be array, object given in ...

这是因为usort工作与数组，而不是对象。你真正想要排序的是一个SEARCH_RESPONSE数组。另外，要注意这个数组中的元素本身是stdClass对象，所以必须使用$a->{$key}符号而不是[]:

function build_sorter($key) {
    return function ($a, $b) use ($key) {
        // pay attention to `{$key}` notation
        return strnatcmp($a->{$key}, $b->{$key});
   };
}
// Get array to sort
usort($response->GetHotelsResult->SEARCH_RESPONSE, build_sorter('ROOMPRICE'));
foreach ($response->GetHotelsResult->SEARCH_RESPONSE as $item) {
    echo $item->ROOMNAME . ', ' . $item->ROOMPRICE . "'n";
}
