        </tr>


<h1>(<?php echo mysql_num_rows($result); ?>)&nbsp&nbspRegistered Member</h1>

That should display the amount of rows fetched from the database.

I you want to use PDO please read this: How to replace MySQL functions with PDO?

You can't access the database with Client-Side JavaScript.

With PHP you can access it by inserting this line after $result=mysql_query("SELECT * FROM tblreg where status = 'reg'");:

echo mysql_num_rows($result);

This way you will get the rows affected by the query.

On the other hand, use mysqli_* or PDO functions, since mysql_* functions are outdated and depracted.

You can find the official documentations on PHP's site:

mysql_num_rows: http://php.net/manual/en/function.mysql-num-rows.php

mysqli_* functions: http://php.net/manual/en/book.mysqli.php

PDO : http://php.net/manual/en/book.pdo.php

UPDATE: In your code just make the $num_rows variable equal to mysql_num_rows($result);

So your code will look something like this:

<?php $query = "SELECT COUNT(*) AS total FROM tblreg where status='reg'"; 
$result = mysql_query($query); 
$values = mysql_fetch_assoc($result); 
$num_rows = mysql_num_rows($result); ?>
