I have modified an authentication script to my own liking, but being new, don't know 
how to go about my next stage.

Once the user has inserted the UN, and PW, it is campared against the MySQL database, 
nowm what i want to do is get rid of the login form which still appears, and is very 
annoying. I can't seem to see anything on this particular subject, but if their is 
any, can u point me in the right direction.

It can be viewed at: http://www.stevewrightonline.co.uk/auth/auth.php
UN: guest
PW: guest

Here's the code:
  <FORM ACTION="<? echo "$PHP_SELF"; ?>" METHOD="POST">
  <input type="text" name="PHP_AUTH_USER" size=15>

  <input type="password" name="PHP_AUTH_PW" size=15>

  <input type="submit" value="Log In">


$auth = false; // user is not authenticated yet

if (isset( $PHP_AUTH_USER ) && isset($PHP_AUTH_PW)) { 

    // Connect the MySQL  Database

    mysql_connect( **************.net', '**********', '***********' ) 
        or die ( 'Unable to connect to server.' ); 

    // Select database on MySQL server 

    mysql_select_db( 'Demonstration' ) 
        or die ( 'Unable to select database.' ); 

    // the query 

    $sql = "SELECT * FROM users WHERE UserName = '$PHP_AUTH_USER' AND Password = 

    // Execute query and put results in $result 

    $result = mysql_query( $sql ) 
        or die ( 'Unable to execute query.' ); 

    // Get number of rows in $result. 

    $num = mysql_numrows( $result ); 

    if ( $num != 0 ) { 

        // matching row was found -  user authenticated. 

        $auth = true; 



if ( ! $auth ) { 
 echo 'Sign In Required.'; 

} else { 

    echo '<p>You are Signed In!</p>';
