<? $url="URL OF THE SITE"; //Fetch the page using the CURL Library $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); $store = curl_exec ($ch); curl_close ($ch); //Print website information (optional) print <<<END <h1>Sitemap links Information for a given website</h1> Website: $url<br /><br /> END; //Strip the Host name from the Url and echo it (used later) preg_match('@^(?:http://)?([^/]+)@i',$url, $matches); $host = $matches[1]; echo '<br />Host: '.$host; //Take out the directory name of your url if(strrpos($url, "/") > 10) $root= substr($url,0,strrpos($url, "/")); else $root= $url; echo '<br />Root: '.$root; //Create an array to save urls $links=array(); //Strip all links from the page preg_match_all('/<a href="(.*)"/U',$store, $matches, PREG_SET_ORDER); //Loop inside the links and rebuild the corresponding full urls. foreach ($matches as $val) { if(strpos($val[1],'#') === FALSE && strpos($val[1],'http://') === FALSE && strpos($val[1],'@') === FALSE) if(!in_array(trim($val[1]),$links)) if(strpos(trim($val[1]),'/') == 0 && strpos(trim($val[1]),'/') !== FALSE) $links[]='http://'.$host.trim($val[1]); else $links[]='http://'.$root.'/'.trim($val[1]); } $date=date('Y-m-d'); //Print all results inside a textarea box: echo '<textarea rows="40" cols="120">'; echo '<?xml version="1.0" encoding="UTF-8"?> <urlset xmlns="http://www.google.com/schemas/sitemap/0.84" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.google.com/schemas/sitemap/0.84 http://www.google.com/schemas/sitemap/0.84/sitemap.xsd"> '; //Loop inside all links and add them to the sitemap using a default priority as 0.9 and a default changefreq as daily. foreach ($links as $val) { print "<url> <loc>$val</loc> <lastmod>$date</lastmod> <changefreq>daily</changefreq> <priority>0.9</priority> </url> "; } print '</urlset>'; echo '</textarea>'; ?>
