This php class will help you generate a sitemap for your website automatically.
// sitemap generator class
class Sitemap{ // constructor receives the list of URLs to include in the sitemap
function Sitemap($items = array()){
$this->_items = $items;
} // add a new sitemap item
function addItem($url, $lastmod = ”, $changefreq = ”, $priority = ”, $additional_fields = array()){
$this->_items[] = array_merge(array(‘loc’ => $url, ‘lastmod’ => $lastmod,‘changefreq’ => $changefreq,‘priority’ => $priority), $additional_fields);
}
// get Google sitemap
function getGoogle(){
ob_start();
header(‘Content-type: text/xml’);
echo ‘<!–l version="1.0" encoding="UTF-8–>’;
echo ‘<urlset xmlns="http://www.google.com/schemas/sitemap/0.84"></urlset>’;
foreach ($this->_items as $i){
echo ‘<url></url>’;
foreach ($i as $index => $_i){
if (!$_i) continue;
echo "<$index>" . $this->_escapeXML($_i) . "";
}
echo ”;
}
echo ”;
return ob_get_clean();
}
// get Yahoo sitemap
function getYahoo(){
ob_start();
header(‘Content-type: text/plain’);
foreach ($this->_items as $i){
echo $i[‘loc’] . "n";
}
return ob_get_clean();
}
// escape string characters for inclusion in XML structure
function _escapeXML($str){
$translation = get_html_translation_table(HTML_ENTITIES, ENT_QUOTES);
foreach ($translation as $key => $value){
$translation[$key] = ‘&#’ . ord($key) . ‘;’;
}
$translation[chr(38)] = ‘&’;
return preg_replace("/&(?![A-Za-z]{0,4}w{2,3};|#[0-9]{2,3};)/","&" , strtr($str, $translation));
}
}
Usage:
$s = new Sitemap();
$s->addItem("http://www.websiteurl.com",
date("Y-m-d"), ‘weekly’, ‘1.0′);
$s->addItem("http://www.websiteurl.com/link2", date("Y-m-d"), ‘weekly’, ‘1.0′);
$s->addItem("http://www.websiteurl.com/link3", date("Y-m-d"), ‘weekly’, ‘1.0′);
This class can create two type of sitemaps for you - XML for Google and TEXT for Yahoo
if(
isset($_GET[‘target’])){
if(($target = $_GET[‘target’]) == ‘google’){
echo $s->getGoogle();//xml sitemap
}elseif($target == ‘yahoo’){
echo $s->getYahoo();//txt sitemap
}
}
This class wasn’t designed by me but by Jaimie Sirovich & Cristian Darie and the reason I put it up here is to help others that are trying to get this done without the headache of creating a new code.
