    注: 
      As of PHP 4.3, this function can (potentially) work on any kind of
      stream.  In PHP 4.3, socket based streams are still the only kind
      supported in the PHP core, although streams from other extensions
      may support this function.
     
     This function was previously called as
     set_socket_timeout() and later
     socket_set_timeout() but this usage is deprecated.
