Laravel 5.1 - Invalid argument supplied for foreach()

And what is the content of the $results or $result variable (depending on which is erroring)?

You can use this to always make it an array in the foreach

foreach ((array) $results as $result) {
    //
}

@bashy Thanks for response.

$results containing

array:8 [▼
  "hits" => array:3 [▶]
  "nbHits" => 3

  "nbPages" => 1

  "processingTimeMS" => 1
  "query" => "arina"
  "params" => "query=arina"

I need to get for example "full_name" form each array, so i make foreach again. but a got an error above.

Don't you want (change it from object to array if required)

$results = Cartalyst\Sentinel\Users\EloquentUser::search('arina');

foreach ((array) $results->hits as $result) {
    echo ($result->full_name);
}

?

@bashy I don't know how i can thank you.. :)

But i just do this

    $results = Cartalyst\Sentinel\Users\EloquentUser::search('arina');
    foreach ((array) $results['hits'] as $result) {
        echo ($result['full_name']);
    }

because this is array not object. Thank you very much..

Yeah just modify as required. Most of the time things will be objects, not sure why that's returning an array but enjoy :)

If my reply helped you, mark it as the best answer. I'd appreciate it!
