對象陣列上的PHP自定義排序Laravel-5

我需要在對象數組上創建自定義排序，但我不知道從哪裏開始。我已經看到函數usort（）等，但我不明白我將如何實現我需要的這些功能。對象陣列上的PHP自定義排序Laravel-5

我的應用程序正在返回下面的對象數組。我需要按以下順序在「槽」字段中排序：全天，上午，下午。

你試過的東西也試過了 –

我還沒有嘗試，所以尋找建議如何處理它。 – V4n1ll4

你可以嘗試這樣的事情

public function index() 
{ 
    $bookingsDate = BookingDate::all() // Your actual collection 
    $this->sortCollection($bookingDate); 
} 
public function sortCollection(\Collection &$bookingDate) 
{ 
    $bookingDate->sortBy(function($date) 
    { 
    $slots = [ 
     'Afternoon' => 1, 
     'Morning' => 2, 
     'All day' => 3, 
    ]; 

    $slot = $slots[$date['slot']]; 


    return $slot; 
    }); 
}

的sortBy方法做一個升序排序，對於降序排序，嘗試sortByDesc

請參閱：http://laravel.com/docs/5.1/collections#method-sortby
