php - how to post a link in facebook (with post method graph api ) -

How do I add a link to the POST

  $ attachment = array ('name' = & gt; $ title, 'link' = & gt; $ link, 'description' = & Gt; "Www.google.it", 'Caption' = & gt; "www.google.it"); $ This- & gt; Facebook- & gt; API ("/ $ UID / feed", 'post', $ attachment);   
 .... are published as link texts, not as clickable links. I use the / PROFILE_ID / feed method and has disabled the security settings of my URL for security of the URL. If you add "http: //" then it will work in [message] and [actions] why does it not work in [caption] or [description]? I would like to know it   'http://www.example.com/image Jpg', ' Actions '= & gt; array (array (' name '= & gt;' http://www.example.com ',' link '= & gt; link')));
