including another view file

[eluser]keevitaja[/eluser]
views i have:

Code:

views/
  /campaigns
    campaign.php
header.php
footer.php

somehow i can't include header.php in campaign.php like include('../header.php')
i found solution:

Code:

include(realpath(sprintf('%s/application/views/header.php', getcwd())));

is this solution OK or i missunderestood something again?
