使用usort＆amp ;;对SOAP Feed进行排序PHP

Question

我正在尝试使用PHP对从SOAP提要中获取的数据进行排序，我现在有这个：

    <?php

$wsdl = "http://portal.letmc.com/PropertySearchService.asmx?WSDL";

$client = new SoapClient($wsdl, array ("trace"=>1, "exceptions"=>0));

$strClientID = "{0050-e58a-cd32-3771}";
$strBranchID = "{0004-e58a-cd32-399e}";
$strAreaID = $_GET['area'];
$nMaxResults = $_GET['perpage'];
$nRentMinimum = $_GET['minrent'];
$nRentMaximum = $_GET['maxrent'];
$nMaximumTenants = $_GET['numtennants'];                           

$parameters = array(    "strClientID"=>$strClientID, 
                    "strBranchID"=>$strBranchID, 
                    "strAreaID"=>$strAreaID, 
                    "nMaxResults"=>$nMaxResults,
                    "nRentMinimum"=>$nRentMinimum,
                    "nRentMaximum"=>$nRentMaximum,
                    "nMaximumTenants"=>$nMaximumTenants
                );                          

$values = $client->SearchProperties($parameters);

if(!is_array($values->SearchPropertiesResult->PropertyInfo))
{
    $values->SearchPropertiesResult->PropertyInfo = array($values->SearchPropertiesResult->PropertyInfo);
}

if($values != '')
{
    $arrayForSort = array();
    foreach ($values->SearchPropertiesResult->PropertyInfo as $message)
    {
        $uglyid = $message->ID;
        $id = $message->FriendlyID;
        $mainphoto = $message->MainPhoto->PhotoUrl;
        $furnished = $message->Furnished;
        $addressline1 = $message->Address1;
        $rooms = $message->MaxTenants;
        $rent = $message->Rent;
        $description = $message->Description;
        $isletagreed = $message->IsLetAgreed;
        $facilities = $message->Facilities->FacilityInfo;
        $photos = $message->Photos->PhotoInfo;
        $roomsinfo = $message->Rooms->RoomInfo;
        $facilitiesstring = serialize($facilities);
        $extractnumbers = ereg_replace("[^0-9]", "", $rent);
        $monthrent = ($extractnumbers) / $rooms;
        $monthrentrounded = number_format(($monthrent/100),2);
        $weekrent = ($monthrentrounded) * 12 / 52;
        $arrayForSort[] = array('weekrent' => $weekrent, 'message' => $message);
        $weekrentrounded = floor($weekrent * 100) / 100;

        $roomsinfojson = json_encode($roomsinfo);
        $facilitiesjson = json_encode($facilities);
        $roomsinfodouble = (substr_count(strip_tags($roomsinfojson),"Double"));
        $roomsinfosingle = (substr_count(strip_tags($roomsinfojson),"Single"));
        $roomsinfobathroom = (substr_count(strip_tags($roomsinfojson),"Bathroom"));
        $roomsinfoshower = (substr_count(strip_tags($roomsinfojson),"Shower"));
        $facilitiesparking = (substr_count(strip_tags($facilitiesjson),"Parking"));
        $facilitiesgarden = (substr_count(strip_tags($facilitiesjson),"Garden"));

        $totalbathrooms = $roomsinfobathroom + $roomsinfoshower;
        $totalimages = count($photos);
                }

        usort($arrayForSort, function($a, $b) {
        if ($a['weekrent'] == $b['weekrent']) {
            return 0;
        }
        return ($a['weekrent'] > $b['weekrent']) ? -1 : 1;
        });

        foreach ($arrayForSort as $item)
        {
             $message = $item['message'];
        echo '
        <div class="col-property-box col-property-box-1-3">
                        <div class="owl-property-box">';
                             $i=0; foreach ($photos as $data) { if($i==4) break; echo '<div class="property-grid-box-picture" style="background: url('. $data->PhotoUrl .') center center;"></div>'; $i++; };
                        echo '</div>

                           </div>
                           <div class="col col-1-4-border">
                            <span class="property-grid-box-number-icon"><center><i class="flaticon-toilet7"></i></center><div class="property-grid-box-number-text">1</div></span>
                           </div>                          
                            <div class="col col-1-4-border">

                </div>
                </div>

            </div>
        ';
    }
}

function limit_words($string, $word_limit)
{
    $words = explode(" ",$string);
    return implode(" ",array_splice($words,0,$word_limit));
}
?> 

这似乎不起作用，我只是多次加载一个属性，我正在尝试使用$ weekrent对数据进行排序。

任何帮助都会很棒！
