Unable to read or post to friends wall (news feed) - php

Question

I have been trying to read a friends news feed to check if my message is there (does not matter if the message is visible, hidden or deleted) and if the message is there, not to post a new message. If it is not there than post a message. The code is below with a lot of unnecessary code to trace where the problem was coming from. I have my permission set for 'publish_stream, read_stream'.
I tried all the code in the other blogs but non seemed to work I do not know whether it is because I am using PHP SDK 3.0 - latest version. My App is iframe app. Even bought an expensive book (too expensive) on Facebook Applications but found out, after buying, that it was out of date!
The code works well if I am using /me or my user id but not my friend's id.
require 'config.php';
require 'facebook.php';
//Create facebook application instance.
$facebook = new Facebook(array(
'appId' => $fb_app_id,
'secret' => $fb_secret
));
$sent = false;
$userData = null;
$PPnotposted = true;
$me = null;
$test_friends =1;
$user = $facebook->getUser();
// Login or logout url will be needed depending on current user state.
if ($user) {
$logoutUrl = $facebook->getLogoutUrl(array("next"=> "<? echo $fb_app_url ?>" ));
} else {
$loginUrl = $facebook->getLoginUrl( array( 'scope'=> 'publish_stream, read_stream', 'redirect_uri' => $fb_app_url));
}
$get_someone_else = 100000xxxxxxxxx; // I used a real user id but covered it up here so
my friend's id hidden for this stackexchange help
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
if ( $get_someone_else ){
$user_profile = $facebook->api("/".$get_someone_else);
echo "<br/> ********************user is ".$get_someone_else." ******************<br/>";
var_dump( $user_profile );
echo "<br/> ********************** end of user info ******************<br/>";
} else {
$user_profile = $facebook->api('/me');
}
} catch (FacebookApiException $e) {
}
// print_r( $user_profile );
$PPaccesstoken = $facebook->getAccessToken();
$attachment[access_token]= $PPaccesstoken ;
//post message to wall if it is sent through form
if(isset($_POST['PPmessage'])){
try {
if( $get_someone_else ){
$ppmy_news = $facebook->api("/.$get_someone_else./feed?limit=300"); //Get 300 messages to examine
echo "<br/> *********************** news feed is ".$ppmy_news." ******************<br/>";
var_dump( $ppmy_news );
echo "<br/> ******************** end of user info ********************<br/>";
} else {
$ppmy_news = $facebook->api('/me/feed?limit=300'); //Get 300 messages
//to examine. Initially I set it to
// 10 messages for testing purposes.
}
// var_dump( $ppmy_news);
// $sent = $facebook->api("/".$user."/feed", 'POST', $attachment );
$ppmy_view_lp=0;
if( $test_friends ) { //Debugging flag to activate or deactivate parts of code
echo "sent is :<br />";
// var_dump( $sent );
echo "<br />";
$friends = $facebook->api('/me/friends');
echo "friends is :<br />";
// var_dump( $friends );
echo "<br />";
$friendsLists = $facebook->api('/me/friends');
$total_friends = 0;
foreach ($friendsLists as $friends) {
foreach ($friends as $friend) {
$id = $friend['id'];
$name = $friend['name'];
$total_friends++; //Get total number of friends
echo "friend : ".$name." id is: ".$id." Total friends is : ".$total_friends." <br/> ";
}
}
}
} catch (FacebookApiException $e) {
echo "<br/> !!!!!!!!!!!! Error Dump Line 85 !!!!!!!!!!!!! <br/>";
var_dump( $e );
echo "<br/> !!!!!!!!!!!! End of Error Dump !!!!!!!!!!!!! <br/>";
//do something about it
}
}
}
But I find I am denied permission and the catch dump is:
!!!!!!!!!!!! Error Dump Line 85 !!!!!!!!!!!!!

Please do help me out and let me know if I have set the permissions wrongly and how to do it properly.

The code is correct, but the problem could lie with Facebook's Privacy Settings. If you can't see the posts on the user's wall, it means that the user has set privacy settings preventing you from seeing the posts.
Use the Graph API Explorer tool (https://developers.facebook.com/tools/explorer/) and see if you can see the user's feed using it. Check a number of friend IDs to see if any of them return data.
