PHP PDO code to start for loop from user defined value

Question

I need to start my for loop from user defined no.

For example, if I enter start:

250, book_no  = 2

it generates data like:

251
251
252
252

What to change in my for loop to work like this?

I tried below code but this does not insert any values and also does not shows error.

 $book_no = $_POST['book_no'];
    for($row1=250;$row1<=$book_no;$row1++)
    {
    $insertrow = $database->insertRow("INSERT INTO scheme_master (book_no) VALUES (:book_no)",  array(':book_no'=>$row1));
    }

Answer 1

 for($row1=$min;$row1<=$max;$row1++)
     {
         for($row=1;$row<=$book_no;$row++)
            {
                $insertrow = $database->insertRow(
                    "INSERT INTO scheme_master
                         (book_no,receipt_no,created) VALUES (:book_no)", 
                    array(':book_no'=>$row1)
                );
            }
        }
