Laravel 数据库只存储值而不存储数组

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

尝试

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

$singlePhoneNumber=$visitorphonenumber->first();

Answer 2

我会在上面的答案中加点糖，使用like

$visitorphonenumber->first()->phonenumber;
