Question

I am new to creating a facebook application and hence started out with a simple Hello World Application. But When I try to display my Name, it is not displayed.

This is my code:

 <?php
   require_once 'facebook.php';

   $api_key = 'mykey';
   $secret = 'mysecretkey';
   $facebook = new Facebook($api_key, $secret);
   $user = $facebook->require_login();

   $fbml      = "<h2>Hello world, my name is <fb:name uid='<?php echo $fb_user;?>'   useyou='false' />,"
       . "welcome to my first facebook application!</h2>";
   echo $fbml;
?>

The output in my facebook app is,

     Hello world,my name is,welcome to my first facebook application!

My name is missing here.

And If I add the code given below,to display the friend’s list,

 $friends = $facebook->api_client->friends_get();
 echo "<pre>Friends:" . print_r($friends, true). "</pre>";

I get the error message,

 Warning: fopen() [function.fopen]: php_network_getaddresses: getaddrinfo failed:
 No such host is known. 
 in C:\Documents and Settings\256148\My Documents\ide\xampplite\htdocs\facebookApp\facebookapi_php5_restlib.php on line 1755

 Warning: fopen(http://api.facebook.com/restserver.php) [function.fopen]:

 No such host is known. in C:\Documents and Settings\256148\My Documents\ide\xampplite\htdocs\facebookApp\facebookapi_php5_restlib.php on line 1755

Please guide me.

I have found a solution for my problem. I had to set the connect url in the application setting to my canvas callback url and created a cross domain communication channel file as given in this tutorial. This tutorial is really very helpful and explains in detail about creating a simple facebook app.

But still I get the Network error when I use $facebook->api_client->friends_get();
