$_SESSION['d_id'] = $d_idd;
$d_id = $_SESSION['d_id'];
//print_r("select * from tbl_multiple_driver where Id = '$d_id'");
die();
$driverUpdate = sqlsrv_query($conn,"select * from tbl_multiple_driver where Id = '$d_id'");
while($driverdetails = sqlsrv_fetch_array($driverUpdate)){
$id = $driverdetails['Id'];
$name = $driverdetails['driver_name'];

On user select you have to pass id again and then update info on base of this id:
$driver_update = "update tbl_multiple_driver set driver_name = '$dName',
driver_mobile='$dMobile',driver_birth_date='$dDob',‌​driver_address='$dAd‌​dress',
location='$dL‌​ocation', city='$dCity',driver_pincode='$dPincode',
PickUp_Area='$dPick‌​Up', vehicle_reg_no='$dVehicleNo' where Id='".$isession['d_id']."' ";
