Hi, munnik,

Plz do the needful. I am sending the following files.

<?php
session_unregister(emp_id);
session_destroy();
echo "session closed for $emp_id";
?>

Authentication.php

<?php
header ("Cache-Control: no-cache, must-revalidate");
header ("Pragma: no-cache");

// Connect to MySQL

mysql_connect( 'localhost', 'balaji', 'pingpong' )
or die ( 'Unable to connect to server.' );

// Select database on MySQL server

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

// Formulate the query

$sql = "SELECT * FROM employee WHERE
emp_id = '$emp_id' AND emp_pass = '$emp_pass'";

// Execute the 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 ) {

// A matching row was found - the user is authenticated.

        $auth = true;
        session_start();
       session_register(emp_id);

$row = mysql_fetch_object($result);

  if ($row->user_type=='S')
  {
              include('super.php');

  }
  else if ($row->user_type=='O')
  {
     include('ordinary.php');

}
}

else
{
file://User does not exist or not authenticated.
   echo '<center><h1>Authorization Required.</h1></center>';
   header( 'WWW-Authenticate: Basic realm="Private"' );
   header( 'HTTP/1.0 401 Unauthorized' );
   exit;
     }

Thanks in advance

With warm Regards

I don't know what's in authentication.php, but I do know that -like
the warningmsg says- you try to send headers while on line 2 you've
already sent some output (echo, print, whatever).
You'll have to put the session_start() before your output.
