How to remove repetitive values from foreach loop in php

Question

Greetings I have an array of sections and the question related to that section looks like this

And I loop through that array and output the content to the screen here is the code

 @foreach($sections as $section)
                    <div class="form-group">
                        <h2>{{ $section['section_name'] }}</h2>
                        <p>{{ $section['section_description'] }}</p>
                        <p>{{ $section['section_intro'] }}</p>
                    </div>
                    <div class="form-group ms-5">
                        @foreach($section['question'] as $question)
                            <h5>{{ $question['question_name'] }}</h5>
                            <p class="ms-3">{{ $question['question_description'] }}</p>
                        @endforeach
                    </div>
                @endforeach

And the result of that looks like this

How can I remove this duplicate question_name I just want it to write it once, for example, it writes one Key Contracts and this two question_description under there for all of them?

 @foreach($sections as $section)
     <div class="form-group">
         <h2>{{ $section['section_name'] }}</h2>
         <p>{{ $section['section_description'] }}</p>
         <p>{{ $section['section_intro'] }}</p>
     </div>
     <div class="form-group ms-5">
         @php
             $questions = [];
             foreach($section['question'] as $question){
                 $questions[$question['question_name']][] = $question['question_description'];
             }
         @endphp
         @foreach($questions as $question_name=>$question_descriptions)
             <h5>{{ $question_name }}</h5>
             @foreach($question_descriptions as $question_description)
                 <p class="ms-3">{{ $question_description }}</p>
             @endforeach
         @endforeach
     </div>
 @endforeach

I haven't tried it but I think it will work. I'm storing the questions and descriptions in an array where the key is not an index but the name.

You could perhaps map the questions into groups by question name before sending to view. Something like this (for example purposes to get you started):

$sections = collect($sections)->map(function($section, $key){
  return [
    "section" => $section,
    "grouped_questions"=> collect($section["question"])->mapToGroups(function($question, $key){
       return [$question['question_name'] => $question];
     })->toArray()
  ];
});

This will give you the questions grouped by their name.
