上载csv文件时出现问题

Question

The csv file will insert new values if the details for the particular month is not already present and it will update the rows with the new datas in the table if the details of the particular month is already present in the table by uploading the csv file.

The last row of the csv file is getting repeated all over the column in the table payslip. I know there is some mistake in my query or something. But i couldnt figure out what is wrong. can anyone please help me solve this issue ?

<?php
require_once '../config.php';

if(isset($_POST['upload']))
{
$fname = $_FILES['sel_file']['name'];
$month = $_POST['month'];
$chk_file = explode(".",$fname);

if(strtolower($chk_file[1]) == 'csv')
{
//$sel=mysql_query("select * from employee where month='$month'");
//$del=mysql_query("delete from employee where month='$month'");
$query1 = mysql_query("SELECT * FROM payslips where month='$month'");
$pay_num_rows = mysql_num_rows($query1);
    $filename = $_FILES['sel_file']['tmp_name'];
    $handle = fopen($filename,"r");
    fgetcsv($handle,1000,",");
    if($pay_num_rows > 1)
    {
    while(($data = fgetcsv($handle,1000,",")) != false)
    {
    $upd = "UPDATE payslips SET    month='$data[9]',tot_work_days='$data[10]',lop_days='$data[11]',arrear_amt='$data[12]',leave_encash='$data[13]' where month='$month'";
    mysql_query($upd) or die(mysql_error());
    }
    fclose($handle);
    echo "Successfully Imported";
}
  if($pay_num_rows == 0)
{
while(($data = fgetcsv($handle,1000,",")) != false)
    {
    $sql = "INSERT into   payslips(employee_code,employee_name,employee_address,emp_dateofjoin,emp_designation,emp_hq,pf_num,esic_num,emp_state,month,tot_work_days,lop_days,arrear_amt,leave_encash) values('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]','$data[5]','$data[6]','$data[7]','$data[8]','$month','$data[10]','$data[11]','$data[12]','$data[13]')";

    //$upd = "UPDATE employee SET  month='$data[9]',tot_work_days='$data[10]',lop_days='$data[11]',arrear_amt='$data[12]',leave_encash='$data[13]' where month='$month'";
    mysql_query($sql) or die(mysql_error());
    }
    fclose($handle);
    echo "Successfully Imported";

}
else
 {
    echo "Invalid File";
}
}
}
