Answer 1

1. Download the Facebook PHP-SDK
2. No need for the offline_access permission

3. Get familiar with the PHP-SDK and use the code in the example page as your index, something like:

   <?php
   require '../src/facebook.php';
   $facebook = new Facebook(array(
     'appId'  => 'XXXXXXX',
     'secret' => 'XXXXXXXX',
     'cookie' => true,
   ));
   
   $session = $facebook->getSession();
   $loginUrl = $facebook->getLoginUrl(array(
       "req_perms" => "publish_stream"
   ));
   $me = null;
   
   if ($session) {
     try {
       $uid = $facebook->getUser();
       $me = $facebook->api('/me');
   
       echo "Welcome User: " . $me['name'] . "<br />";
   
       $post_id = $facebook->api("/$uid/feed", "post", array("message"=>"Hello World!"));
       if(isset($post_id))
           echo "A new post to your wall has been posted with id: $post_id";
   
     } catch (FacebookApiException $e) {
       error_log($e);
     }
   } else {
       echo("<script> top.location.href='" . $loginUrl . "'</script>");
   }
   ?>
