Dear all,

I would like to check with you guys whether any comments will be given.

I have created an index login page with the following code.

<?php

if (!isset($PHP_AUTH_USER)) {

  header('WWW-Authenticate: Basic realm="Security Login!"');
  header('HTTP/1.0 401 Unauthorized');
  echo '<br><br><div align="center"><font color="#FF0000" face="Verdana, Arial, Helvetica, sans-serif">Sorry, This site is strictly confidential !</font></div><br><br>';
  echo ' ';
  echo '<div align="center"><font color="#FF0000" face="Verdana, Arial, Helvetica, sans-serif">You are not authorized to access this site....., please check with your administrator.</font></div>';
  echo '<br><br><br><br><br><div align="center"><font color="#000000" face="Verdana, Arial, Helvetica, sans-serif">Copyright Tecsys Product Ž 2003. All Rights Reserved</font></div><br><br>';
  exit;

} else if (isset($PHP_AUTH_USER)) {

mysql_connect("localhost", "username", "password")

or die ("Unable to connect to database.");

// select database on MySQL server

mysql_select_db("sales")
or die ("Unable to select database.");

// Formulate the query

  $sql = "SELECT *
                FROM user
                WHERE username='$PHP_AUTH_USER' and password='$PHP_AUTH_PW'";

// Execute the query and put results in $result

$result = mysql_query($sql);

  // Get number of rows in $result. 0 if invalid, 1 if valid.
  while ($row = mysql_fetch_array($result)) {

  $PHP_AUTH_USER = $row['username'];
  $PHP_AUTH_PW = $row['password'];
  $name = $row['name'];
  }

  $num = mysql_numrows($result);

  if ($num == "0") {

  header('WWW-Authenticate: Basic realm="Security Login!"');
  header('HTTP/1.0 401 Unauthorized');
  echo '<br><br><div align="center"><font color="#FF0000" face="Verdana, Arial, Helvetica, sans-serif">Sorry, This site is strictly confidential !</font></div><br><br>';
  echo ' ';
  echo '<div align="center"><font color="#FF0000" face="Verdana, Arial, Helvetica, sans-serif">You are not authorized to access this site....., please check with your administrator.</font></div>';
  echo '<br><br><br><br><br><div align="center"><font color="#000000" face="Verdana, Arial, Helvetica, sans-serif">Copyright Tecsys Product Ž 2003. All Rights Reserved</font></div><br><br>';
  exit;

  } else

  if ($num != "0") {

   session_start();
   session_register('user');
   $user = "yes";
   session_register('user_login');
   $user_login = "$name";
   header("Location:content.php");
   exit;

}

}
?>

My session will register as above, but for my logout / log off page..the code as below:

<?
session_start();
session_unset($user);
session_unset($user_login);
session_destroy();
header("Location: http://192.168.1.1/sales/logout_msg.php");

After logout, i try to login again, but it straight away go in to the content page without asking me to enter the username and password. May I know what's wrong ? Any help ? thanks,

Besides, my second problem is the mail function. I have coming out a script "mail () " function. Even the script the is running but no email received, may i know other than mail () function, anyway to do email scripting by using PHP ?

thanks in advance,

Regards,

Winson Kee
