I recently came across this blog post that said that it\'s possible to tag someone in a status update from a Facebook app (= from the API):
However, it doesn\'t seem
below code worked for me , try if you don't want to show place in post then use the same code i mentioned $params['place']='155021662189'; that code won't show the place in Post
$params=array();
$params['message'] = "Hi Friends ";
$params['tags']='12345678903,1234567654'; //comma separated friends ID's
$params['place']='155021662189';
$params['name'] = "Some namee";
$params['link'] = "http://blaha.com";
$params['description'] = "blah blah blah blah";
$params['picture'] = "image link";
$params['caption'] = "Join ";
$shared=$facebook->api("/".$user['id']."/feed", "post", $params);
or
$shared=$facebook->api("/me/feed", "post", $params);
