load xmms config via php

hi,

I am trying to launch xmms via php...using this command:
 exec('bash -c "xmms -p /home/adam/mp3/* > /dev/null 2>&1 &"');

It loads ok, but because apache runs as www-data then xmms is unable to
find the config as there is no ~/.xmms/config

Is there anyway of forcing xmms to load a specififc config file, say in a
local dir in the htdocs tree?
