Setting environment variables for accessing in PHP when using Apache

Something along the lines:

<VirtualHost hostname:80>
   ...
   SetEnv VARIABLE_NAME variable_value
   ...
</VirtualHost>

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 MY_ENV_NAME=myEnvValue

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;
