Using Linux Environment Variables in PHP

Question

I am using Windows 7 Ultimate, PHP 5.2, VMWare (with Ubuntu Server V11.04)

My plan is to create an environment variable in both the linux and windows platforms, and to make them work in PHP. So I created the variable "ROOT_DIR" in Windows and another "ROOT_DIR" variable in Windows.

I have this code in PHP that I expect to work in both the platforms:

<?php
echo 'My username is ' .$_ENV["ROOT_DIR"] . '!';
?>

But in Linux, all it outputs is NULL. I wonder what I'm doing wrong here. Any help would be appreciated.

I suspect this not PHP, but Linux/bash question. How did you define the variable? Did you use "export"? — ualinker

I have tried getenv and it also didn't work. Yes I have used "export". — Aldrin Dela Cruz

If you are running the script through the browser then try adding the following to your main .htaccess file

SetEnv ROOT_DIR "/path/to/root/"

apache setenv

seems like I don't have a .htaccess file inside the /var/www folder. Can I just create one?

This worked. But I had to use _SERVER instead of _ENV. Or maybe I could edit my windows' htaccess so i can use _SERVER in windows as well. Where is the htaccess in Windows?

You can create a new one and place it in your root directory.

i did but it didn't work. Is there any file I should edit so that .htaccess would work?

Try adding an invalid command/text/code to the .htaccess and see if the server will be affected (by responding with with code 500). This is a way to tell that the .htaccess is actually read by the server
