I have a php based website http://www.darooadda.com. I want to know if there is any facebook API to invite friends from facebook account. If a user logins the webite using facebook account, he should be able to invite his facebook friends from the website.

Can anyone help me with the correct api documentation or sample php code for the same?

    this sample code can use facebook API 3.0.1, request friends and post back to your site if request sent

    $<?php
// Requires Facebook PHP SDK 3.0.1: https://github.com/facebook/php-sdk/
require ('includes/facebook.php');
define('FACEBOOK_APP_ID',"your facebook ID");
define('FACEBOOK_SECRET',"your facebook secret password");

$user = null;

// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => FACEBOOK_APP_ID,
'secret' => FACEBOOK_SECRET,
'cookie' => true
));

$user = $facebook->getUser();
$loginUrl = $facebook->getLoginUrl();

if ( empty($user) ) {
echo("<script> top.location.href='" . $loginUrl . "'</script>");
exit();
}
?>
<!doctype html>
<html>
<head>
  <title>Send An Application Request Using The Facebook Graph API</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>

</head>
<body>
 <div id="fb-root"></div>


<a href="#">Send Application Request</a>

<script>
  window.fbAsyncInit = function() {
    FB.init({
      appId: '<?php echo $facebook->getAppID() ?>',
      status: true,
      cookie: true,
      oauth: true
    });
  };

  $('a').click(sendRequest);
  function sendRequest() {
    FB.ui({
      method: 'apprequests',
      message: 'Check out this application!',
      title: 'Send your friends an application request',
    },
    function (response) {
      if (response.request && response.to) {
        var request_ids = [];
        for(i=0; i<response.to.length; i++) {
          var temp = response.request + '_' + response.to[i];
          request_ids.push(temp);
        }
        var requests = request_ids.join(',');
        $.post('handle_requests.php',{uid: '<?php echo $user; ?>', request_ids: requests},function(resp) {
          // callback after storing the requests
        });
      } else {
        alert('canceled');
      }
    });
    return false;
  }

  // Load the SDK Asynchronously
  (function(d){
    var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
    js = d.createElement('script'); js.id = id; js.async = true;
    js.src = "//connect.facebook.net/en_US/all.js";
    d.getElementsByTagName('head')[0].appendChild(js);
  }(document));
</script>
