Validate Sum up array field from foreach Laravel

Question

Currently I have working foreach array where it collects all tasks and it contains weight for each task.

Here's my working code

foreach ($arr4 as $row4) {
    $taskCode = strtoupper(str_random(12));
    $insert_data5[] = array(
        'projCode'  =>  $projCode,
        'taskCode'  => $taskCode,
        'taskWeight'  =>  $row4['weight'],
        'plan_days' =>  $row4['planned_days'],
        'actual_days'  =>  $row4['actual_days'],
        'deleted'  =>  0,
        'by_id'  => auth()->user()->id,
        'updated_by'    =>  auth()->user()->name,
        'created_at'    =>  now(),
        'updated_at'    => now(),
        );

}

dd($insert_data5);

OUTPUT

What I'm trying to do is to validate if the sum up of taskWeight of 5 Tasks doesn't reached 100% this will show an error message.

As of now my idea is to use validator but I have no idea how can I calculate the array fields of taskWeight

  $validator = Validator::make(
                $insert_data5,
                [
                   ......
                ]
            );


   if($validator->fails()){
                return redirect()
                ->back()
                ->with(['errors'=>$validator->errors()->all()])
                ->with('modal',$modal);
            }

What do you want here? did you mean to ask how to limit total sum of taskWeight to be less than 100? and what does that 5 Tasks mean? did you mean to say you want sum of 5 tasks or there are total 5 tasks? — Pusparaj

I mean, if I sum up all the tasks using taskWeight this should not exceeds 100%. I just want to limit the total sum up into 100% and if the total sum up of taskWeight is <100 there's a validation will appear that says it should be exact 100% — Pablo

Fixed my problem

I declare $ttlTaskWeight = 0; outside of foreach

Then as suggested do the sum up inside of the foreach

like this

$ttlTaskWeight += $row4['weight'];

and I did this to validate if it exceeds 100% or not

    if($ttlTaskWeight != 100){
                return redirect()
                ->back()
                ->with(['errors'=> [0=> 'Total Task Weight must be exact 100%']])
                ->with('modal',$modal);
            }

and the output is this
