Question: I want to get the current location in longitude and latitude in Android 8.0+ when the app is running and I don't want to display notification as we have in the background services. 

I was previously using background location services in android below 8.0 but in 8.0 we need to show a notification.

Answer: 
declare `$phone` variable out side of while loop 

```
$phone ='';
while($row = $get_result->fetch_assoc())
            {
                  if($phone) {
                       $phone .=','.$row['dnr_phone']; 
                  } else {
                       $phone .=$row['dnr_phone']; 
                  }

                  echo $phone;
           }

```
Due to above code, $phone takes only last mobile number,because sendSMS function called after while loop.

Solution::
sendSMS("Pname",$phone,$message);
This function should be in while loop.
