What are the best practices for generating XML feeds with PHP to avoid link parsing issues?

When generating XML feeds with PHP, it is important to properly escape special characters in URLs to avoid parsing issues. One common issue is with ampersands (&) in URLs, which can break the XML structure if not properly encoded. To solve this problem, use PHP's htmlspecialchars function to encode special characters, including ampersands, before adding URLs to the XML feed. 

// Sample code snippet to generate XML feed with properly encoded URLs
$xml = new SimpleXMLElement('<feed></feed>');

// Sample URL with ampersand
$url = 'https://example.com/page.php?id=123&name=John';

// Encode URL using htmlspecialchars
$encoded_url = htmlspecialchars($url, ENT_QUOTES, 'UTF-8');

$item = $xml->addChild('item');
$item->addChild('link', $encoded_url);

echo $xml->asXML();
