I want to check either the countries exist in countries and the checkbox will be displayed. The values is directly from the database. I can't set the value at the input since it is array/multiple values. So, I want to check every array so that it will be a checkbox. 

**Controller :**

```
public function edit($id)
{
    $region = Region::find($id);
    $countries = Country::all();
    $country_region = DB::table('regions')
        ->select('countries.id', 'countries.name')
        ->join('country_region', 'regions.id', '=', 'country_region.region_id')
        ->join('countries', 'country_region.country_id', '=', 'countries.id')
        ->where('regions.id', '=', $id)
        ->get();

    $items = array(
        'region' => $region,
        'countries' => $countries,
        'country_region' => $country_region,
    );

    return view('admin.region.edit')->with($items);
}

```

**blade**

```
<div class="form-group">
    <label>Choose Country</label>
    <select id="test" type="checkbox" name="country_id[]">
        @foreach ($countries as $item)
        <option value="{{$item->id}}" selected @if (in_array($item->id, array_keys($country_region))) checked="checked"
            @endif>{{$item->name}}
        </option>
        @endforeach
    </select>
</div>

```

As you can see, I put php statement inside the blade to check either $country\_region is exist in the countries or not. I got errors that related to the array such below : 

```
array_keys() expects parameter 1 to be array, object given
