Creating A PHP Sitemap XML Script - php

Question

I have a database driven website that I add to every day & I want to make an xml sitemap for google with php but I'm really unsure of how to do this. Using the code that I'm used to I created this:
<?php
$get_articles_sql = "SELECT * FROM articles ORDER BY added DESC";
$get_articles_res = mysqli_query($con, $get_articles_sql);
while($article = mysqli_fetch_assoc($get_articles_res)){
$article_id = $article["id"];
$article_title = $article["title"];
$article_added = $article["added"];
$article_date = date('Y-M-D', strtotime($article_added));
$article_url_title = preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%&-]/s', '', $article_title);
$article_url_title = strtolower(str_replace(" ","-",$article_url_title));
$list_articles .= "
<url>
<loc>http://www.website.com/article.php?id=$article_id&title=$article_url_title</loc>
<lastmod>$article_date</lastmod>
<changefreq>monthly</changefreq>
<priority>0.8</priority>
</url>
";
?>
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>http://www.website.com</loc>
<lastmod>2005-01-01</lastmod>
<changefreq>daily</changefreq>
<priority>1.0</priority>
</url>
<?php echo $list_articles; ?>
</urlset>
However, this returns an error on the <?xml line. Is there a correct way of doing it using the code method that I'm using?

Answer 1

Your server probably has short tags enabled which causes the <? in the XML declaration to throw a parse error. The easiest work around is to just echo that line out.
echo '<?xml version="1.0" encoding="UTF-8"?>'
?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
It also looks like you're missing the closing bracket to your while loop but I am assuming that is merely a typo.
