How to figure the question into 100 in relationship in laravel - php

Question

I have two models 1. Subject 2. Question and it has One to many relation. And a student can choose many subjects he want. And now I want to take a test through the subjects. And the test should be 100 marks test.Now i need a way how to accomplish the 100 marks test. Suppose a student choose 3 subjects and if we divide 3 form 100 then it will be 33 (floor) or 34 (ceil) per subject but i want to round it to 100, how i accomplish this. Here is my code for getting the questionsn
foreach ($student->departments as $key => $department){
$majorSubjects[] =$department->subject_id;
}
$no_of_questions =100;
$uniqueSubjects=array_unique($majorSubjects);
$div = ceil($no_of_questions/count($uniqueSubjects));
$mul = $div*count($uniqueSubjects);
$subjects=Subject::whereIn('id',$majorSubjects)->get();
}
and in my blade
#foreach($subjects as $key => $subject)
<li class=" {{$key == 0 ? 'active' : ''}}">{{$subject->name}}</li>
#endforeach
</ul>
<div class="tab-content">
#if(!empty($subjects))
#foreach($subjects as $key => $subject)
<div class="tab-pane {{$key == 0 ? 'active' : ''}}" id="tab_{{ $subject->id }}">
#foreach($subject->questions->random($div) as $num => $question)
<form></form>
#endforeach

Answer 1

You can use modulus to get the remaining mark test.
$additional_mark_test = $no_of_questions % count($uniqueSubjects);
Put it in here.
foreach ($student->departments as $key => $department){
$majorSubjects[] =$department->subject_id;
}
$no_of_questions =100;
$uniqueSubjects=array_unique($majorSubjects);
$div = ceil($no_of_questions/count($uniqueSubjects));
$mul = $div*count($uniqueSubjects);
// Get the remaining test
$additional_mark_test = $no_of_questions % count($uniqueSubjects);
$subjects=Subject::whereIn('id',$majorSubjects)->get();
}
In your blade, this will check first if $additional_mark_test is empty.
#if(!empty($additional_mark_test))
#foreach($subject->questions->random($additional_mark_test) as $num => $question)
<form></form>
#endforeach
#php $additional_mark_test = 0; #endphp
#endif
Put it in here.
#foreach($subjects as $key => $subject)
<li class=" {{$key == 0 ? 'active' : ''}}">{{$subject->name}}</li>
#endforeach
</ul>
<div class="tab-content">
#if(!empty($subjects))
#foreach($subjects as $key => $subject)
<div class="tab-pane {{$key == 0 ? 'active' : ''}}" id="tab_{{ $subject->id }}">
#foreach($subject->questions->random($div) as $num => $question)
<form></form>
#endforeach
<!--Additional Mark Test(This will be add to first subject)-->
#if(!empty($additional_mark_test))
#foreach($subject->questions->random($additional_mark_test) as $num => $question)
<form></form>
#endforeach
#php $additional_mark_test = 0; #endphp
#endif
