Laravel数据库仅存储值而不是数组

Question

$visitorphonenumber=DB::select('select phonenumber from visitortable where email=?',[Auth::user()->email]);

$booking=new bookingmodel();
$booking->visitorphonenumber=$visitorphonenumber;

这会将[{"phonenumber":"9874589608"}]之类的值存储在数据库中，但我只想存储9874589608

Answer 1

我会在上面添加一些糖，就像

一样

$visitorphonenumber->first()->phonenumber;

Answer 2

尝试

$visitorphonenumber=DB::select('select phonenumber from visitortable where email=?',[Auth::user()->email]);

$singlePhoneNumber=$visitorphonenumber->first();
