title: Is it possible to redirect using PHP?
body: <p>I am trying to redirect user on die() to a different place. Like for example if user hits cancel he will be redirected to say tryagain.php or if he enters incorrect credentials he will be redirected to resetpassword.php</p>
  
  <p>Please guide me so that I can achieve that.</p>
  
  <p>How do I achieve that. Here's my code below:</p>
  
  <pre><code>&lt;?php
  $realm = 'Restricted area';
  
  //user =&gt; password
  $users = array('admin' =&gt; 'mypass', 'guest' =&gt; 'guest');
  
  
  if (empty($_SERVER['PHP_AUTH_DIGEST'])) {
      header('HTTP/1.1 401 Unauthorized');
      header('WWW-Authenticate: Digest realm="'.$realm.
             '",qop="auth",nonce="'.uniqid().'",opaque="'.md5($realm).'"');
  
      die('Text to send if user hits Cancel button');
  }
  
  
  // analyze the PHP_AUTH_DIGEST variable
  if (!($data = http_digest_parse($_SERVER['PHP_AUTH_DIGEST'])) ||
      !isset($users[$data['username']]))
      die('Wrong Credentials!');
  
  
  // generate the valid response
  $A1 = md5($data['username'] . ':' . $realm . ':' . $users[$data['username']]);
  $A2 = md5($_SERVER['REQUEST_METHOD'].':'.$data['uri']);
  $valid_response = md5($A1.':'.$data['nonce'].':'.$data['nc'].':'.$data['cnonce'].':'.$data['qop'].':'.$A2);
  
  if ($data['response'] != $valid_response)
      die('Wrong Credentials!');
  
  // ok, valid username &amp; password
  echo 'You are logged in as: ' . $data['username'];
  
  
  // function to parse the http auth header
  function http_digest_parse($txt)
  {
      // protect against missing data
      $needed_parts = array('nonce'=&gt;1, 'nc'=&gt;1, 'cnonce'=&gt;1, 'qop'=&gt;1, 'username'=&gt;1, 'uri'=&gt;1, 'response'=&gt;1);
      $data = array();
      $keys = implode('|', array_keys($needed_parts));
  
      preg_match_all('@(' . $keys . ')=(?:([\'"])([^\2]+?)\2|([^\s,]+))@', $txt, $matches, PREG_SET_ORDER);
  
      foreach ($matches as $m) {
          $data[$m[1]] = $m[3] ? $m[3] : $m[4];
          unset($needed_parts[$m[1]]);
      }
  
      return $needed_parts ? false : $data;
  }
  ?&gt;
