Help What is happening in this code?

Hi.. I have this code and I'm not quite understand what exacly is happening here.
So could someone explain it to me? ;)

Code:
if (!isset($HTTP_POST_VARS) && isset($_POST))
{
	$HTTP_POST_VARS = $_POST;
	$HTTP_GET_VARS = $_GET;
	$HTTP_SERVER_VARS = $_SERVER;
	$HTTP_COOKIE_VARS = $_COOKIE;
	$HTTP_ENV_VARS = $_ENV;
	$HTTP_POST_FILES = $_FILES;
}

if (get_magic_quotes_gpc())
{
	if (!empty($_GET))    { $_GET    = strip_magic_quotes($_GET);    }
	if (!empty($_POST))   { $_POST   = strip_magic_quotes($_POST);   }
	if (!empty($_COOKIE)) { $_COOKIE = strip_magic_quotes($_COOKIE); }
}

if( !get_magic_quotes_gpc() )
{
	if( is_array($HTTP_GET_VARS) )
	{
		while( list($k, $v) = each($HTTP_GET_VARS) )
		{
			if( is_array($HTTP_GET_VARS[$k]) )
			{
				while( list($k2, $v2) = each($HTTP_GET_VARS[$k]) )
				{
					$HTTP_GET_VARS[$k][$k2] = addslashes($v2);
				}
				@reset($HTTP_GET_VARS[$k]);
			}
			else
			{
				$HTTP_GET_VARS[$k] = addslashes($v);
			}
		}
		@reset($HTTP_GET_VARS);
	}

	if( is_array($HTTP_POST_VARS) )
	{
		while( list($k, $v) = each($HTTP_POST_VARS) )
		{
			if( is_array($HTTP_POST_VARS[$k]) )
			{
				while( list($k2, $v2) = each($HTTP_POST_VARS[$k]) )
				{
					$HTTP_POST_VARS[$k][$k2] = addslashes($v2);
				}
				@reset($HTTP_POST_VARS[$k]);
			}
			else
			{
				$HTTP_POST_VARS[$k] = addslashes($v);
			}
		}
		@reset($HTTP_POST_VARS);
	}

	if( is_array($HTTP_COOKIE_VARS) )
	{
		while( list($k, $v) = each($HTTP_COOKIE_VARS) )
		{
			if( is_array($HTTP_COOKIE_VARS[$k]) )
			{
				while( list($k2, $v2) = each($HTTP_COOKIE_VARS[$k]) )
				{
					$HTTP_COOKIE_VARS[$k][$k2] = addslashes($v2);
				}
				@reset($HTTP_COOKIE_VARS[$k]);
			}
			else
			{
				$HTTP_COOKIE_VARS[$k] = addslashes($v);
			}
		}
		@reset($HTTP_COOKIE_VARS);
	}
}
