I need to build a custom sort on an object array but i'm not sure where to start. I've seen the functions usort() etc but I can't see how i'd implement these functions for what I require.
My application is returning the below object array. I need to order it by the "slot" field in the following order: All Day, Morning, Afternoon.

You can try something like this
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;
});
}
The sortBy method will do an ascending sort, for descending sort, try sortByDesc
