Path Problem

donnierivera

My paths for my include files works perfect on my WinNT (main/sub/sub) development box, but when I move my scripts to the UNIX box they don’t work. I have played with the following:
• $DOCUMENT_MUM
• $DOCUMENT_ROOT
• $_SERVER["DOCUMENT_ROOT"]

But they hold no value when I echo the variables. Is this because my php.ini file’s include_path = ".:/php/includes" is not set correctly or is there something with Apache’s config file I need to set? Or does anyone have a different idea? Thanks for any idea’s…

GOT IT! 1) Need to add my root dir to php.ini include_path =".:/php/includes:/docnet/web;." 2) Which took me forever to figure out? When calling $DOCUMENT_ROOT in a function. You must make it global. hmm... Don't quit understand since it is a system variable, but I guess it makes since because I called it in a function. Hope this helps someone from lack documentation (at least I couldn’t find any other than forum questions and responses) on $DOCUMENT_ROOT and how to set the value…

I just had the same issue and it did turn out that I needed to declare $DOCUMENT_ROOT as global in the function. I guess since it is treated as a normal variable and read into the global namespace that it only adds up that if used in a function it needs to be declared global just like any other variable.

thanks for posting your answer after you figured it out.

$DOCUMENT_ROOT is indeed set by the system to be the document root of your website, but is only available in the global scope, i.e. outside of functions.

To use any of these variables you MUST declare them as global before using them (the same goes for $PHP_SELF, $HTTP_POST_VARS etc etc).

The only variables which you can use without having to do this first are what PHP calls Superglobals. Go take a read on pre-defined variables on the PHP manual at http://www.php.net/manual/sv/language.variables.predefined.php
