How can PHP scripts securely connect to a server and retrieve XML data?

To securely connect to a server and retrieve XML data in PHP, you can use cURL to make the HTTP request over HTTPS. This ensures that the data transfer is encrypted and secure. Additionally, you can parse the XML response using SimpleXML or another XML parser library to extract the necessary information. 

// Initialize cURL session
$ch = curl_init();

// Set cURL options for HTTPS connection
curl_setopt($ch, CURLOPT_URL, 'https://example.com/data.xml');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);

// Execute the cURL session and store the XML response
$xml_data = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Parse the XML response
$xml = simplexml_load_string($xml_data);

// Access and display the desired XML data
echo $xml->node->subnode;
