Thanks, although these instructions don't match the version I downloaded, all the classes are stored in various folders, starting:
\Classes\Phpdocx\
with CreateDocx in:
\Classes\Phpdocx\Create
so to get working I added:
require_once 'Classes/Phpdocx/Create/CreateDocx.inc';
but no other functions work, unless I create further includes:
require_once 'Classes/Phpdocx/Elements/WordFragment.inc';
So any ideas on how to resolve this please?
