[PHP] On Universal File Download Class

I'd refactor all the "action" methods out in separate classes.
All those methods share similarity in variables they use and logging.

// untested, and my PHP is verrry rusty...

class CCAction
{
	const FAIL = "FAIL";
	const SUCCESS = "SUCCESS";
	
	protected $url;
	protected $method;
	
	public function fetch()
	{
		if(!isset($this->url))
		{
			$this->log(CCAction::FAIL, "No url set")
		}
		
		if($this->check_prerequisites())
		{
			if($this->do_fetch())
			{
				$this->log(CCAction::SUCCESS, "File has been downloaded using ".$this->method);	
			}
			else
			{
				$this->log(CCAction::FAIL, "Could not downloaded file using ".$this->method);
			}
		}
	}
	
	protected function log($status, $message)
	{
		$this->log_status(date("H:i:s d-m-Y")." $status : $message");
	}
}

class CCGetUsingCurl extends CCAction
{
	protected $method = "wget";
	
	public function __init($url)
	{
		$this->url = $url;
	}
	
	protected function check_prerequisites()
	{
		// check for curl, etc
	}
	
	protected function do_fetch()
	{
		// do the actual fetching
	}
}

[Ruby] to_xml, with explicit and conditional removal of a :include

2009-01-13T16:30:53-08:00

If offline_at is before now, explicitly remove :data from :includes passed to to_xml
So, if offline_at > Time.now, and args = { :include => :data}, old_to_xml will be called with { :include => [] }

alias_method :old_to_xml, :to_xml
def to_xml(args={})
  if args[:include]
    if offline_at && offline_at <= Time.now
      args[:include] -= [:data]
    end
  end
  old_to_xml(args)
end
