What is the relationship between XML, RSS, and PHP in web development?

XML is a markup language used for storing and transporting data. RSS (Rich Site Summary) is a format for delivering regularly changing web content. PHP is a server-side scripting language commonly used in web development. In web development, PHP can be used to parse XML data, including RSS feeds, and display it on a website. 

<?php
$xml = simplexml_load_file('rss_feed.xml');
foreach ($xml->channel->item as $item) {
    echo '<h2>' . $item->title . '</h2>';
    echo '<p>' . $item->description . '</p>';
}
?>
