kendi sitemde kullandığım sitemap.php :

<?php
include_once('fonksiyon.php');
echo '<?xml version="1.0" encoding="ISO-8859-9"?>

    </url>';
$katcek = mysql_query("SELECT katseo FROM kategori ORDER BY sira ASC");
$drivercek = mysql_query("SELECT id,baslikseo FROM driver ORDER BY id ASC");
$markacek = mysql_query("SELECT markaseo FROM marka ORDER BY marka ASC");
while(list($katseo) = mysql_fetch_array($katcek)) {

htaccess dosyasına da aşşağıdaki kodu ekleyerek bunu sitemap.xml olarak gösteriyorum. umarım işine yarar

ReWriteRule ^sitemap.xml$ sitemap.php [L,NC]
