I just started to try the Dynamic Virtual Hosts for Apache. All is
good, but when I have a PHP script that relies on
$_SERVER["DOCUMENT_ROOT"] to access some include files, it failed. The
value being reported back is the top Document Root defined in the
Apache conf file, something like '/var/www', instead of the correct
value of '/var/www/domain.com/'.

Does this mean that I cannot rely on the Document Root value when the
site is managed under Dynamic Virtual Host?

Thanks.

Try declaring your document root

For Example:

<host 10.0.0.1>
....
DocumentRoot /usr/home/user/html
....
</host>

Thanks. But you did not understand my question. i am using Dynamic
Virtual Host, not the normal virtual host. So what you just said does
not apply.

Hi

look up VirtualDocumentRoot at http://httpd.apache.org/

we use

VirtualDocumentRoot /home/domain/users/%2.1/%2.2/%2/web

If by "dynamic virtual host" you mean some mass-vhosting solution,
then yes.

With normal vhosts, apache keeps information for each host in a separate
object. That includes both simple stuff like document root and more
expensive stuff like file descriptors for the logs. That's great for
a small number of hosts, but doesn't scale well to larger numbers.
So mass-virtual-hosting uses a single server_rec for all vhosts.

Thanks! But how do you get around it then? Like I said, my PHP script
relies on the $_SERVER["DOCUMENT_ROOT"] value so that it can includes
other files correctly. If under mass vhosting, Apache does not report
that document root anymore, then my script is broken. I hate to go back
and change all the include path to relative, just thinking about all
those "../../../../" is driving me nuts.

Is there any way to have Apache report the correct document root even
using mass vhosting?

Thanks again.

Depending on how you've set up mass virtual hosting, maybe you can
concatenate:

$docroot = $_SERVER["DOCUMENT_ROOT"] . "/" . $_SERVER["SERVER_NAME"]

Adjust to suit your configuration.

Thanks guys! i guess i cannot rely on Apache any more. i will have to
figure something out. because i also want the script to be portable.
meaning when migrated to other hosting environment that use normal
vhosting, it will still work.

thanks!
