Assuming you have the user's access_token(which you can get via $facebook->getAccessToken() after you've logged a user in:

try{
    $permissions = $facebook->api('/me/permissions', 'get', array('access_token'=>$access_token));
    print_r($permissions, true);
    if(empty($permissions['data'][0]['installed'])){
        echo 'User has not installed the application.';
    }
    if(empty($permissions['data'][0]['publish_stream'])){
        echo 'User does not have the publish_stream permission.';
    }
}catch(Exception $e){
    echo $e->getMessage();
}
