What resources or documentation should PHP developers refer to when working with cURL functions for XML interfaces to ensure compatibility and avoid errors?

When working with cURL functions for XML interfaces in PHP, developers should refer to the official PHP documentation for cURL functions and the specific XML interface documentation to ensure compatibility and avoid errors. It is important to understand the parameters required for making successful cURL requests and how to properly handle XML data returned from the interface. 

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

// Set cURL options for XML interface
curl_setopt($ch, CURLOPT_URL, 'https://example.com/xml_interface');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute cURL request
$response = curl_exec($ch);

// Check for errors
if($response === false){
    echo 'cURL error: ' . curl_error($ch);
}

// Close cURL session
curl_close($ch);

// Process XML data
$xml = simplexml_load_string($response);
// Use $xml object for further processing
