排序數組PHP PHP usort

-1

我想排序我的數組輸出$ weekrent，我有這個到目前爲止，但我得到輸出是重複相同的數據，而不是它的順序。有沒有其他方法可以做到這一點，以便我可以根據變量排列數據？排序數組PHP PHP usort

$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); 
       } 

     foreach ($arrayForSort as $item) 
     { 
      usort($arrayForSort, function($a, $b) { 
      return $a['weekrent'] - $b['weekrent']; 
     }); 
      $message = $item['message']; 
     echo '$addressline1'; 
    } 
}

任何幫助將是偉大的！

什麼是代碼中的$ a和$ b？ –

無需多次對數組進行排序。刪除'foreach（$ arrayForSort as $ item）'，只保留對它包含的'usort（）的調用。如果'$ arrayForSort'沒有正確排序，那麼確保你在'weekrent'中輸入的值是正確的。我不會使用'$ monthrentrounded'（這不是一個四捨五入的數字，而是一個字符串），但是隻使用數字來計算'$ weekrent'。如果需要舍入，則使用該功能適當的功能。它的名字是（還有什麼？）['round（）']（http://php.net/manual/en/function.round.php）。 – axiac

如果你的數組包含key/index，那麼你可以使用uasort（）php函數。

$sort = uasort($arrayForSort, function($a, $b) 
     { 
      return $b['weekrent'] - $a['weekrent']; 
     } 
);

，如果你要排序多個元素，那麼你可以使用下面的代碼：

$sort = uasort($arrayForSort, function($a, $b) 
     { 
      $c = $b['weekrent'] - $a['weekrent']; 
      $c .= $b['id'] - $a['id']; 
      return $c; 
     } 
);

然後，你將不得不打印arrayForSort，你將得到的結果。

printr($arrayForSort);
