Array help

Hi,

I have this simple script.
I need to define more than 1 user for this and also assign name for the username.

Any ideas ?

<?php
session_start();

$username = "user1";
$password = "pass1";
$name = "User";


if(isset($_GET['logout']))
{
  unset($_SESSION["login"]);
  echo "You have logged out ... ";
  echo "[<a href='index.php'>Login</a>]";
  exit;
}

if (!isset($_SERVER['PHP_AUTH_USER']) || !isset($_SERVER['PHP_AUTH_PW']) || !isset($_SESSION["login"]))
{
  header("WWW-Authenticate: Basic realm=\"Agents\"");
  header("HTTP/1.0 401 Unauthorized");
  $_SESSION["login"] = true;
  echo "You are unauthorized ... ";
  echo "[<a href='index.php'>Login</a>]";
  exit;
}
else
{
  if($_SERVER['PHP_AUTH_USER'] == $username && $_SERVER['PHP_AUTH_PW'] == $password)
  {
echo "Welcome $name";
  }
  else
  {
    unset($_SESSION["login"]);
    header("Location:index.php");
  }
}

?> 

PHP:

 

Try this:

<?php
  session_start();
  
  //array of username => password
  $login_info = array('user1' => 'pass1');
  
  if (isset($_GET['logout'])) {
      unset($_SESSION["login"]);
      echo "You have logged out ... ";
      echo "[<a href='index.php'>Login</a>]";
      exit;
  }
  
  if (!isset($_SERVER['PHP_AUTH_USER']) || !isset($_SERVER['PHP_AUTH_PW']) || !isset($_SESSION["login"])) {
      header("WWW-Authenticate: Basic realm=\"Agents\"");
      header("HTTP/1.0 401 Unauthorized");
      $_SESSION["login"] = true;
      echo "You are unauthorized ... ";
      echo "[<a href='index.php'>Login</a>]";
      exit;
  } else {
      if (array_key_exists($_SERVER['PHP_AUTH_USER'], $login_info) && $login_info[$username] == $_SERVER['PHP_AUTH_PW']) {
          echo "Welcome {$_SERVER['PHP_AUTH_USER']}";
      } else {
          unset($_SESSION["login"]);
          header("Location:index.php");
      }
  }
?>

PHP:

You can edit $login_info to add more 'accounts'.

 

Thanks verymuch for the effort.
But the code does not work.
I mean it does not accept the username & pass.
Tried a few different ways but still could not get it to work..

Any ideas ?

 

I just modified your code, theirfore it should'nt effect functionality, however I rewrote your code here you go:

<?php
  session_start();
  //array of username => password
  $login_info = array('admin' => 'pass', 'danx10' => 'dppass');
 
  $file = basename(__FILE__);
  if (isset($_GET['logout'])) {
      unset($_SESSION["username"]);
      unset($_SESSION["login"]);
      header("Location: {$file}");
  }
 
  if (!isset($_SESSION['login'])) {
      if (isset($_POST['submit'])) {
          $username = $_POST['username'];
          $password = $_POST['password'];
          $errors = array();
          if (strlen($username) <= 1) {
              $errors[] = "The username is too short.";
          }
          if (strlen($password) <= 1) {
              $errors[] = "The password is too short.";
          }
         
          if (!array_key_exists($username, $login_info) || $login_info[$username] != $password) {
              $errors[] = "Username or password are incorrect";
          }
         
          if (empty($errors)) {
              $_SESSION["username"] = $username;
              $_SESSION["login"] = true;
              header("Location: {$file}");
          } else {
              $out = "<ul>";
              foreach ($errors as $error) {
                  $out .= "<li>{$error}</li>";
              }
              $out .= "</ul>";
              echo $out;
          }
      } else {
?>
<form method="post">
Username: <input type="text" name="username"><br />
Password: <input type="password" name="password"><br />
<input type="submit" name="submit" value="Login">
</form>
<?php
      }
  } else {
?>
Hello <?php
      echo $_SESSION["username"];
?>, you are logged in<br />
<a href="?logout">Logout?</a>
<?php
      /* private content should go here */
  }
?>

Thanks danx10, it worked just fine..

One extra question. If I was to add a detail for that user, ie. membership number or some detail to print on the secure content, how would I do it ?
Something like " $login_info = array('admin' => 'pass' => '4223', 'danx10' => 'dppass' =>'4224'); "
