Laravel Collection ordered by day of the week M-F - php

Question

I have a Laravel collection grouped by day of the week but they are in the wrong order. I need them ordered by day of the week starting with Monday.
My Controller:
public function getWeeklySchedule()
{
$testSchedule = VolunteerSchedule::all();
$result = $testSchedule->groupBy(['assignment', function ($item) {
return $item['scheduled_days'];
}]);
return $result;
}
The result looks like this:

Some fields have been removed for brevity. The days of the week are stored as a serialized array in the database. What is the best way to accomplish this?

Answer 1

Just define a custom sort function that uses a map for the days of the week:
$days = ["Monday" => 1, "Tuesday" => 2, "Wednesday" => 3, "Thursday" => 4, "Friday" => 5, "Saturday" => 6, "Sunday" => 7];
$collection = collect(["Friday" => [], "Wednesday" => [], "Tuesday" => []]);
$collection->sortBy(fn($val, $key) => $days[$key]);
dump($collection);
Output:
=> Illuminate\Support\Collection {#4977
all: [
"Tuesday" => [],
"Wednesday" => [],
"Friday" => [],
],
}
So your code becomes:
public function getWeeklySchedule(): Collection
{
$days = ["Monday" => 1, "Tuesday" => 2, "Wednesday" => 3, "Thursday" => 4, "Friday" => 5, "Saturday" => 6, "Sunday" => 7];
return VolunteerSchedule::all()
->groupBy(['assignment', fn ($item) => $item['scheduled_days']])
->sortBy(fn ($val, $key) => $days[$key]);
}

Answer 2

It will 100% work. It will sort collection from monday to sunday.
$ProductAvailabilities =ProductProductAvailability:get();
$days = [
'monday'=>1,
'tuesday'=>2,
'wednesday'=>3,
'thursday'=>4,
'friday'=>5,
'saturday'=>6,
'sunday'=>7
];
$sortingDays = array();
foreach($days as $day => $value)
{
$sortingDays[] = $ProductAvailabilities->where('day_availability',$day);
}
$ProductAvailabilities=collect($sortingDays)->flatten();
