Zend Framework Google Login Example

Here is an example of how you can use Zend Framework to allow your users to log into your site using their Google Account access details.

<?php
 session_start();

 $email = isset($_REQUEST['email']) ? $_REQUEST['email'] : null;
 $password = isset($_REQUEST['password']) ? $_REQUEST['password'] : null;
 $captchaToken = isset($_REQUEST['captchatoken']) ? $_REQUEST['captchatoken'] : null;
 $captchaText = isset($_REQUEST['captchatext']) ? $_REQUEST['captchatext'] : null;

 if ($email && $password) {
  require_once 'Zend/Loader.php';
  Zend_Loader::registerAutoload();
  try {
   $client = Zend_Gdata_ClientLogin::getHttpClient($email, $password, 'xapi', null, 'Zend-ZendFramework', $captchaToken, $captchaText);
   $_SESSION['email'] = $email;
  } catch (Zend_Gdata_App_CaptchaRequiredException $e) {
   $captchaToken = $e->getCaptchaToken();
   $captchaUrl = $e->getCaptchaUrl();
  } catch (Zend_Gdata_App_AuthException $e) {
   $error = $e->getMessage();
  }
 }

 if (isset($_SESSION['email'])) {
  header('Location: profile');
  exit;
 }
?>
<!DOCTYPE HTML>
<html lang="en">
 <head>
  <title>Zend Framework Google Login Example</title>
 </head>
 <body>
  <h1>Zend Framework Google Login Example</h1>
  <?php if (isset($error)): ?>
   <p><?php echo htmlspecialchars($error); ?></p>
  <?php endif; ?>
  <form method="post">
   <p><label for="email">Email:</label> <input id="email" name="email" type="text" value="<?php echo htmlspecialchars($email); ?>"></p>
   <p><label for="password">Password:</label> <input id="password" name="password" type="password"></p>
   <?php if (isset($captchaUrl)): ?>
    <div><input type="hidden" name="captchatoken" value="<?php echo htmlspecialchars($captchaToken); ?>"></div>
    <p><img src="<?php echo htmlspecialchars($captchaUrl); ?>" alt=""></p>
    <p><label for="captchatext">Text:</label> <input id="captchatext" name="captchatext" type="text"></p>
   <?php endif; ?>
   <p><button type="submit">Login</button></p>
  </form>
 </body>
</html>

I just don't want to have my password travel through somebody else's system. Surely there must be a better way? Can't we just do it like with Google App Engine?
