Recently I needed to use the xml-rpc lib with symfony. I created a function to make cache of xml-rpc requests using the symfony's sfFileCache and it work good.

I'm using the xml-rpc library that you can get on http://phpxmlrpc.sourceforge.net/

public function callCache( $methodName, $params ){
  // generated a key to cache file
  $key = $methodName."_".implode('_', $params->getval() );
  $cache = new sfFileCache( array( 'cache_dir' => sfConfig::get('sf_cache_dir')."/xmlrpc/" ) );
  // check if already exist the cache file 

  if( ! $cache->has( $key ) ){
    //init xml-rpc message/
    $f = new xmlrpcmsg($methodName, $params);
    $f->addParam($params);
    $c = new xmlrpc_client("/xml-rpc", $this->host, 443, 'https' );
    $c->setCredentials($this->username, $this->password);
    $c->setDebug( $this->debug );
    $response = $c->send($f);
    $cache->set( $key , serialize( $response ), 3600);
  }else{
    $response = $cache->get( $key );
    $response = unserialize( $response );
  }
 
  if( ! $response->value() ){
    $this->erro( $response->errno, $response->faultString() );
  }
  $results = php_xmlrpc_decode( $response->value() );
  $this->rows = count($results);
  $this->data = $results;
 
}
