<?php
 include("dbconn.inc");
 $data=mysql_query("SELECT `subtitle`, `mian-title`, `page_num`, `note_path`, `flash_path` FROM `main-page` WHERE `page_num` =".$r." LIMIT 1");
echo $data;
if (mysql_num_rows($data) == 0) {
echo "No rows found, nothing to print so am exiting";
exit;
 }
 while ($row = mysql_fetch_assoc($data))
{       echo $row['page_num'];
}
include("close.php"); 
 ?>
