<?xml version="1.0" encoding="UTF-8">
 <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">
  <url>
    <loc>http://www.phponwebsites.com</loc>
<lastmod>today date<lastmod>
<changefreq>daily</changefreq>
<priority>1</priority>
  </url>
  <url>
    <loc>http://www.phponwebsites.com/p/htaccess.html</loc>
<lastmod>today date<lastmod>
<changefreq>daily</changefreq>
<priority>1</priority>
  </url>
 </urlset>

  where,
      urlset - encapsulates the file ie, start sitemap
      url - parent tag for each entry ie, each page
      loc - location of url
      lastmod - date for last modification of file
      changefreq -  how frequently the pag is changed. It should be always, hourly, daily, monthly, weekly, yearly, never
      priority - priority of url. It should be between 0.0 to 1.0

Create sitemap dynamically using PHP and MySQL:


                          First you need to add content type for xml to generate sitemap in PHP. ie,

 header ("content-type: text/xml");


                        Then add contents to XML file. Then save this file as sitemap.php .


<?php
 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('new') or die(mysql_error());
 $dat=date('Y-m-d');
 header ("content-type: text/xml");
 echo '<?xml version="1.0" encoding="UTF-8"?>
 <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">';
 $urls=mysql_query("select * from url")or die(mysql_error());
 while($row_Tags=mysql_fetch_array($urls))
 {
   echo "<url><loc>".$row_Tags['url']."</loc><lastmod>".$dat."</lastmod><changefreq>daily</changefreq><priority>1</priority></url>";
 }
  echo "</urlset>";
 ?>


.htaccess:

               
               In your .htaccess, you add following codes.

RewriteRule ^sitemap.xml sitemap.php [L]

                   When you run sitemap.xml on your website each time,  it display upto date contents.
