I have some problems setting a environment variable in the php-fpm pool config file.
When I set env[SOMENAME] = somevalue in my /etc/php5/fpm/pool/www.conf file php can not get the value with $_SERVER['SOMENAME']. Are there some config settings I have to set in apache/php to get the value from that environment variable?
Merge Fiete's answer with Kufner's and you get the correct one.
Somewhere in Apache, you want to set an environment variable somehow:
SetEnv SOME_VAR "a value"
or with Rewrite:
RewriteRule ^ - [E:SOME_VAR="a value"]
Your PHP script (according to phpinfo()) will have this variable for you in the $_SERVER array.
You can set your environment variables in /etc/apache2/envvars.
Only add the following line in the config file and restart your apache.
export SOMENAME=somevalue
after that you can access it via $_SERVER['SOMENAME'] in PHP.
In Apache configuration, you can use SetEnv directive. And for PHP FPM, you have it right.
But environment variables are not available in $_SERVER, they are in $_ENV variable. So you should see your somevalue in $_ENV['SOMENAME'].
$_SERVER is the primary place to read environment variables. Yes, it is very poorly named. Also see this: stackoverflow.com/questions/3780866/why-is-my-env-empty
$_ENV. The $_SERVER contains much more data than only the env variables so you cannot be sure from where the values arrived.$_SERVER contains additional variables, not just the environment. But the environment is always in there, which is unfortunately not true for $_ENV, depending on the PHP configuration.
