  1. Create App Developer Facebook Page.

Live Access token you can get via graph. Then code exmaple:

<ul>
<?php

$page_name = '{PAGE_NAME}'; // Example: http://facebook.com/{PAGE_NAME}
$page_id = '{PAGE_ID}'; // can get form Facebook page settings
$app_id = '{APP_ID}'; // can get form Developer Facebook Page
$app_secret = '{APP_SECRET}'; // can get form Developer Facebook Page
$limit = 5;

function load_face_posts($page_id, $page_name, $app_id, $app_secret, $limit, $message_len) {
    $access_token = "https://graph.facebook.com/oauth/access_token?client_id=$app_id&client_secret=$app_secret&grant_type=client_credentials";
    $access_token = file_get_contents($access_token); // returns 'accesstoken=APP_TOKEN|APP_SECRET'
    $access_token = str_replace('access_token=', '', $access_token);
    $limit = 5;
    $data  = file_get_contents("https://graph.facebook.com/$page_name/posts?limit=$limit&access_token=$access_token");
    $data = json_decode($data, true);
    $posts = $data[data];
    //echo sizeof($posts);

    for($i=0; $i<sizeof($posts); $i++) {
        //echo $posts[$i][id];
        $link_id = str_replace($page_id."_", '', $posts[$i][id]);
        $message = $posts[$i][message];

        echo ($i+1).". <a target='_blank' href='https://www.facebook.com/AqualinkMMC/posts/".$link_id."'>".$message."</a><br>";
    }
}

load_face_posts($page_id, $page_name, $app_id, $app_secret, $limit, $message_len);
?>
</ul>

If you have a valid access token, you can get feed from any public page using php graph api.You can call api using file_get_contents or curl method.

function curl_get_file_contents($URL) {
$ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, $URL);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,0); 
 curl_setopt($ch, CURLOPT_TIMEOUT, 400);
 $contents = curl_exec($ch);
 $err  = curl_getinfo($ch,CURLINFO_HTTP_CODE);
 curl_close($ch);
$contents=json_decode($contents,true);
if ($contents) return $contents;
else return FALSE;
}

$access_token = 'your accesstoken';
$url = " https://graph.facebook.com/$page_id/feed?access_token=$access_token";
$posts = curl_get_file_contents($url);

Now $posts will have all the recents posts from the page and you can use foreach to get each post.

In order to read the Feed from Facebook, you must log the user into Facebook and ask the user for the read_stream permission.

The feed will be the logged-in user's feed and may not be appropriate for all users of your website, unless each user of your website sees their own feed...
