Laravel - Advanced Sum Aggregate in Laravel Eloquent - laravel

Question

I have this table in mysql:
student_payment : id, student_class(varchar), student_code(varchar), gender(varchar), amount(float), created_at (timestamp)
Model name is is StudentPayment
What I want to achieve is that:
If student_class is JSS1, it checks the amount paid by each gender and place it in the respective column
If student_class is JSS2, it checks the amount paid by each gender and place it in the respective column
If student_class is SSS1, it checks the amount paid by everyone, both male and female
If student_class is SSS2, it checks the amount paid by everyone, both male and female
It sums everything vertically and horizontally
It groups everything by date (created_at)
I have this query in my Controller, but don't know how to continue
$students = DB::table('student_payment')
->select(
'student_class',
'gender',
'amount',
DB::raw('DATE(created_at) as created_date')
)
->orderByRaw('created_at DESC');
The result I want to achieve is as shown below:
How do I complete this query in the controller to achieve this result. Thanks

Answer 1

Following Code will give you grouping of student payment data,
$payments = DB::table('student_payment')->orderBy('created_at', 'DESC')->get();
$data = [];
foreach ($payments as $payment){
if($payment->gender=="male"){
$data[$payment->student_class]['male'][] = $payment->amount;
}elseif($payment->gender=="female"){
$data[$payment->student_class]['female'][] = $payment->amount;
}
}
Now you can calculate the sum of amounts using array_sum function. For example,
If you want to calculate payment of JSS1 class female student then,
array_sum(data['JSS1']['female']);
This will give the sum of payment. You can calculate like this for other as well.
