What are the potential pitfalls and solutions when dealing with gzipped XML data retrieved through HTTPS requests in PHP using cURL?

Issue: When dealing with gzipped XML data retrieved through HTTPS requests in PHP using cURL, the potential pitfall is that the response may be compressed and need to be decompressed before parsing the XML data. One solution is to set the appropriate cURL options to handle the gzip encoding and then use PHP's `gzdecode` function to decompress the response before processing the XML data.

// Set cURL options to handle gzip encoding
curl_setopt($ch, CURLOPT_ENCODING, '');

// Make HTTPS request
$response = curl_exec($ch);

// Decompress the response if it is gzipped
if (strpos($response, "\x1f\x8b\x08") === 0) {
    $response = gzdecode($response);
}

// Process the XML data
$xml = simplexml_load_string($response);
