Serializing Models & Collections
Serializing To Arrays

To convert a model and its loaded relationships to an array, you should use the toArray method. This method is recursive, so all attributes and all relations (including the relations of relations) will be converted to arrays:

$user = App\User::with('roles')->first();
return $user->toArray();

$users = App\User::all();
return $users->toArray();

$user = App\User::find(1);
return $user->toJson();
return $user->toJson(JSON_PRETTY_PRINT);

Hiding Attributes From JSON
Sometimes you may wish to limit the attributes, such as passwords, that are included in your model’s array or JSON representation. To do so, add a $hidden property to your model:

namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = ['password'];
}
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
    /**
     * The attributes that should be visible in arrays.
     *
     * @var array
     */
    protected $visible = ['first_name', 'last_name'];
}
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
    /**
     * Get the administrator flag for the user.
     *
     * @return bool
     */
    public function getIsAdminAttribute()
    {
        return $this->attributes['admin'] == 'yes';
    }
}
namespace App\Providers;
use Illuminate\Support\Carbon;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
    /**
     * Perform post-registration booting of services.
     *
     * @return void
     */
    public function boot()
    {
        Carbon::serializeUsing(function ($carbon) {
            return $carbon->format('U');
        });
    }

    /**
     * Register bindings in the container.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}
