How can PHP be used to automate the process of fetching and parsing website content for an RSS feed?

To automate the process of fetching and parsing website content for an RSS feed using PHP, you can use the SimplePie library. SimplePie allows you to easily fetch and parse RSS feeds from websites. You can then use SimplePie's functions to extract the necessary information from the feed and display it on your website.

// Include the SimplePie library
require_once('simplepie/autoloader.php');

// Create a new SimplePie object
$feed = new SimplePie();

// Set the feed URL
$feed->set_feed_url('https://example.com/feed');

// Initialize the feed
$feed->init();

// Set the number of items to display
$feed->set_item_limit(10);

// Loop through each item in the feed
foreach ($feed->get_items() as $item) {
    // Output the title and link of each item
    echo '<a href="' . $item->get_permalink() . '">' . $item->get_title() . '</a><br>';
}
