It is also possible to use the Zend_InfoCard component as a
standalone component by interacting with the
Zend_InfoCard class directly. Using the
Zend_InfoCard class is very similar to its use with the
Zend_Auth component. An example of its use is shown below:
<?php
if (isset($_POST['xmlToken'])) {
$infocard = new Zend_InfoCard();
$infocard->addCertificatePair('/usr/local/Zend/apache2/conf/server.key',
'/usr/local/Zend/apache2/conf/server.crt');
$claims = $infocard->process($_POST['xmlToken']);
if($claims->isValid()) {
print "Given Name: {$claims->givenname}<br />";
print "Surname: {$claims->surname}<br />";
print "Email Address: {$claims->emailaddress}<br />";
print "PPI: {$claims->getCardID()}<br />";
} else {
print "Error Validating identity: {$claims->getErrorMsg()}";
}
}
?>

<form method="post">
<input type="submit" value="Login" />
<object type="application/x-informationCard" name="xmlToken">
<param name="tokenType"
value="urn:oasis:names:tc:SAML:1.0:assertion" />
<param name="requiredClaims"
value="http://.../claims/givenname
http://.../claims/surname
http://.../claims/emailaddress
http://.../claims/privatepersonalidentifier" />
</object>
</form>
</div>
In the example above, we use the Zend_InfoCard component
independently to validate the token provided by the user. As was the
case with the Zend_Auth_Adapter_InfoCard, we create an
instance of Zend_InfoCard and then set one or more
SSL certificate public/private key pairs used by the web server. Once
configured, we can use the process() method to process
the information card and return the results.
