Publish on page wall with PHP SDK - php

Question

I need my application to publish a post on my Wall page automatically and for that use PHP-SDK, but the publication does not appear. Until the notification that the publication occurred, but it does not appear in the Wall page. In the same script, if I change the page_id by "me" the publication is made in the wall of my profile perfectly.
See code:
$fb_page_id = 'xxxxxxxxxx';
$fb_app_id = 'xxxxxxxxxxxxxxxxxxxx';
$fb_secret = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$fb_app_url = 'https://apps.facebook.com/application/';
$fb_app_baseUrl ="http://www.mysite.com/app/application/";
$msg = array(
'message' => 'date: ' . date('Y-m-d') . ' time: ' . date('H:i')
);
//construct the message/post by posted data
$msg['message'] = 'Test';
$msg['link'] = $link;
$msg['picture'] = "http://www.mysite.com/app/facebook/icone_75_75.jpg";
$msg['name'] = $titulo;
$msg['caption'] = '';
$msg['description'] = $texto;
$msg['actions'] = array( array('name' => 'test', 'link' => 'http://www.mysite.com'));
//Create facebook application instance.
$facebook = new Facebook(array(
'appId' => $fb_app_id,
'secret' => $fb_secret
));
try {
$facebook->api('/'.$fb_page_id.'/feed', 'POST', $msg);
} catch (FacebookApiException $e) {
print_r($e);
}
thanks.
Now I created a database for storing received tokens. I used the token to post, but did not work!
