Two associative arrays of different lengths, how to compare values ​​and apply to checkboxes?

Question

Laravel

There are two associative arrays of different lengths, how to compare their values ​​and apply them to checkboxes? So that if the values ​​match, that checkbox gets the attribute checked. Now I get it like this:

• Politics
  
• Video (checked)
  
• Politics (checked)
  
• Video
  

And I want

• Video (checked)
  
• Politics (checked)
  

Here is the code, but in it, I'm doing something wrong, can you help

@foreach($category as $categories)
                <input type="checkbox" aria-label="{{$categories->title}}" value="{{$categories->title}}" name="category[{{$categories->id}}]"> {{$categories->title}}

                @foreach($post->category as $selected)
                    @if($selected->title == $categories->title)
                    <input type="checkbox" aria-label="{{$categories->title}}" value="{{$categories->title}}" name="category[{{$categories->id}}]" checked> {{$categories->title}}
                    @endif
                @endforeach


            @endforeach

Answer 1

Hmmm, if I understood the problem correctly, then

@foreach($category as $categories)
                @foreach($post->category as $selected)
                    @if($selected->title == $categories->title)
                    <input type="checkbox" aria-label="{{$categories->title}}" value="{{$categories->title}}" name="category[{{$categories->id}}]" checked> {{$categories->title}}
                    @endif
                @endforeach


            @endforeach
