Send mail with password to all students

Thanks for your fast reply.

but i need to send emails in the while loop.

Code:

$query = "SELECT * FROM `mail`";
$result = mysql_query($query);

  while ($row = mysql_fetch_array ($result))
  {
     $mail->Body    = "Your password is : dynamic values";
     $mail->AddAddress($row['email']);
     $mail->Send();
  }

it sends multiple mails to every users in the records..
but it doesn't have any duplicate records in the database..

or is there any simple way??

thanks
