I am storing some response from a third party. Sometimes data is not storing in to database. I checked the Laravel log and getting some error. I am using laravel 5.5 and mongo db.

Couple of ways you can handle that. One of them is to use utf8-encode

string utf8_encode ( string $data )

PaymentController.php

$payment = new Payment;

   foreach($_POST as $key => $value) {
     if(Schema::hasColumn($payment->getTable(), $key)){
        if(is_array($value)) {
           $payment->{$key} = utf8_encode($value[1]);//changes
        } else 
        {
                    $payment->{$key} = utf8_encode($value);//changes

        }

        }
        }
    $payment->save();
