[php] Setting environment variables for accessing in PHP when using Apache

I have a Linux environment and I have a PHP Web Application that conditionally runs based on environment variables using getenv in PHP. I need to know how these environment variables need to be set for the application to work correctly. I am not sure how to set this up on Apache.

Also, I need to be able to configure separate environment variables for each domain separately.

Please advice on how can I achieve this.

Unbelievable, but on httpd 2.2 on centos 6.4 this works.

Export env vars in /etc/sysconfig/httpd

export mydocroot=/var/www/html

Then simply do this...

<VirtualHost *:80>
  DocumentRoot ${mydocroot}
</VirtualHost>

Then finally....

service httpd restart;

You can also do this in a .htaccess file assuming they are enabled on the website.

SetEnv KOHANA_ENV production

Would be all you need to add to a .htaccess to add the environment variable

If your server is Ubuntu and Apache version is 2.4

Server version: Apache/2.4.29 (Ubuntu)

Then you export variables in "/etc/apache2/envvars" location.

Just like this below line, you need to add an extra line in "/etc/apache2/envvars" export GOROOT=/usr/local/go
