Laravel array to json format

You could return an json_encoded array from the controller like so:

public function index()
{
    $posts = Post::all();
    $json = json_encode($posts);
    return View::make('posts.index', compact('posts', 'json'));
}

Which you then can work on in your view like you'd like:

<script type="text/javascript">
    var data = {{ $json }};
    console.log(data);
</script>

Also, if you have sensitive fields on your post model, you should exclude these in the model class to prevent them to show in your javascript inspector:

class Post extends \Eloquent {
    ...

    protected $hidden = array(
    'id',
    'created_at',
    'updated_at'
    );

    ...
}

Use Eloquents built in function toJson to get your rows as json.

<script type="text/javascript">
   var data = "{{ $posts->toJson() }}";
   console.log(data);
</script>

If there's some fields you don't want to include, add the field to the hidden property in your model as Jimmy mentioned.

If you looking for "high-level" way to convert plain array to json, you can use laravel collections.

collect(['a' => 1, 'b' => 2, 'c' => 3])->toJson();
