php - Object of class stdClass could not be converted to string - laravel -

but raises exception:

  object of class stdclass not converted string 

what doing wrong ?

update:

tried this:

$data = get_object_vars($data);

get_object_vars() expects parameter 1 object, array given 

this:

$data = (array)$data;
