Nedense, bu değişken alışkanlık ekran için. İşte kod:

<?php
require_once("functions/redirect.php");
require_once("functions/connect.php");
require_once("queries/member-table-query.php");

$id = $_GET["id"];

// Query the db to get all of the info to put in the XML file
$result  =  mysql_query("SELECT members.* FROM members JOIN $nombre ON     members.member_ID=$nombre.friends") or die(mysql_error());
 $number  =  mysql_num_rows($result);


$xmlout  =  "<?xml version='1.0' encoding='ISO-8859-1'?><Peers>";
while($msg = mysql_fetch_assoc($result))
{
 $xmlout .= "<friend lang='en'>
     <name>".$msg['first_name']." ".$msg['last_name']."</name>
     <url>petition_invite_member.php?petition_ID=$id&  amp;member_ID=".$msg['member_ID']."  </url>
     <photo>".$msg['photo']."</photo>
     <location>".$msg['home_state']." - ".$msg['district']."</location>
    </friend>";
}
$xmlout .= "</Peers>";
?>

Nedense, $ id değişkeni url etiketleri arasında göstermez.

Herhangi bir fikir? Teşekkürler
