HTTP_ENV_VARS + Cobalt RAQ3i

Hi All, I'm using php4.0.1pl2 on a Cobalt RAQ3i and I'm having difficulties with HTTP_ENV_VARS[]. I haven't used php4 on unix before, so I'm not sure if this is specific to the RAQ or not, but the Apache Environment variables are not listed in the Environment section of phpinfo() and do not get hashed in HTTP_ENV_VARS[]. To further complicate things the RAQ seems to log (or do something with) HTTP errors like 404 and so periodically there are a whole bunch of Apache Environment variables registered in HTTP_ENV_VARS[] however these are related to the virtual host which generated the error and not the current virtual host, they're also short lived. So things like HTTP_ENV_VARS["DOCUMENT_ROOT"] gives incorrect information or nothing at all. From limited testing it appears that getenv gets the correct DOCUMENT_ROOT even when HTTP_ENV_VARS["DOCUMENT_ROOT"] is returning an incorrect one or is unset. Can anyone with a greater understanding of the php internals clarify for me if I'm going to get the right answer consistently from getenv()? Is there an order of precedence for env vars and apache env vars? Currently I'm moving a project which was developed on windows and relies heavily on HTTP_ENV_VARS[]. Is there a way to force the Apache env vars to be included in this hash and give them priority over any env vars of the same name? This appears to be what happens on win32. BTW I realise I can, but I'd rather not turn register_globals on Thanks, Andrew
