//convert text url into links.
function make_links_to_text_url($text, $class='', $target='_blank'){
    return preg_replace('!((http\:\/\/|ftp\:\/\/|https\:\/\/)|www\.)([-a-zA-Zа-яА-Я0-9\~\!\@\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\'\,]*)?!ism', '<a class="'.$class.'" href="//$3" target="'.$target.'">$1$3</a>', $text);

 define("PAGE_ID",'Your Page ID');

 $config = array(
  'appId' => YOUR_APP_ID,
  'secret' => YOUR_APP_SECRET,    
  );
 $api = new Facebook($config);
 $posts = $api->api("/".PAGE_ID."/posts?limit=10");
 ?>

<?php
foreach ($posts['data'] as $post){
echo "<p>";
echo make_links_to_text_url($post['message']);
