htmlentities() expects parameter 1 to be string, array given, Json_decode ;

Question

I have problem. I can't print value of $value->working type unicode in foreach but that not working and i have notification htmlentities() expects parameter 1 to be string, array given I'm using Json. When i echo dd($levelResult) then

array:1 [▼
  0 => "Đại Học"
]

if i echo $levelResult[0] then i have notification Invalid argument supplied for foreach()

@foreach( $search as $key => $value)
    @if(json_decode($value->working,JSON_BIGINT_AS_STRING)[0] != " ")           
         @foreach(json_decode($value->working) as $key => $levelResult)
               <p>{{ $levelResult }} </p>               
         @endforeach
    @else
      {{ " " }}
    @endif
@endforeach

To fix your second issue use json_decode($value->working, true) to parse json in array but not in object.

I would suggest you yo use the following code snippet. The code will parse json once and proper if comparison.

@foreach( $search as $key => $value)
    <?php $result = json_decode($value->working, true, 512, JSON_BIGINT_AS_STRING); ?>
    @if($result[0] != " ")
        @foreach($result as $key => $levelResult)
                   <p>{{ $levelResult[0] }} </p>
        @endforeach
    @else
      {{ " " }}
    @endif
@endforeach

@Andreyj Ludinovskov: i used code of you but i still see notification

htmlentities() expects parameter 1 to be string, array given at htmlentities(array('Đại Học'), '3', 'UTF-8', false) in helpers.php line 531

i don't know why it's not working :'(

@BiHíp does it make sense to check $result[0] != " " if it's array always?
