我目前使用此 PHP 从肥皂提要中提取数据，无论如何我是否可以使用 $weekrent 中的数据从高到低对结果进行排序？
任何帮助都会很棒！这是我的PHP代码：
<?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($values != '')
{
foreach ($values->SearchPropertiesResult->PropertyInfo as $message)
{
$uglyid = $message->ID;

$monthrent = ($extractnumbers) / $rooms;
$monthrentrounded = number_format(($monthrent/100),2);
$weekrent = ($monthrentrounded) * 12 / 52;
$weekrentrounded = floor($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"));

你可以使用usort函数..所以你得到排序的结果

您可以将消息数据与计算的周租金一起放入临时数组中，然后使用 usort 按周租金值对 desc 进行排序
if($values != '')
{
$arrayForSort = array();
foreach ($values->SearchPropertiesResult->PropertyInfo as $message) {
$rent = $message->Rent;
$rooms = $message->MaxTenants;
$extractnumbers = ereg_replace("[^0-9]", "", $rent);
$monthrent = ($extractnumbers) / $rooms;
$monthrentrounded = number_format(($monthrent/100),2);
$weekrent = ($monthrentrounded) * 12 / 52;
$arrayForSort[] = array('weekrent' => $weekrent, 'message' => $message);
}
usort($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'];
// Your code here to proper process the message ...
