What are the potential pitfalls of using fsockopen() and xmlrpc_encode/xmlrpc_decode for XMLRPC communication in PHP?

Potential pitfalls of using fsockopen() and xmlrpc_encode/xmlrpc_decode for XMLRPC communication in PHP include potential security vulnerabilities due to manual handling of socket connections and XML data. To mitigate these risks, it is recommended to use built-in PHP functions like xmlrpc_encode_request() and xmlrpc_decode() which handle the XMLRPC communication more securely. 

// Using built-in PHP functions for XMLRPC communication
$request = xmlrpc_encode_request('methodName', array('param1', 'param2'));
$context = stream_context_create(array(
    'http' => array(
        'method' => "POST",
        'header' => "Content-Type: text/xml",
        'content' => $request
    )
));
$response = file_get_contents('http://example.com/xmlrpc', false, $context);
$result = xmlrpc_decode($response);
