_ENV["APACHE_LOG_DIR"]  /var/log/apache2
_ENV["PWD"]                 /

Answer 1

Assuming the variables are exported under the correct user, $_ENV should contain them.

See: http://se.php.net/manual/en/reserved.variables.environment.php

Answer 2

Trying to set an environment variable for a daemon process is trickier than it sounds. Only interactive login bash shells source /etc/profile, which probably doesn't match the criteria of your web server process. See this page for more information.

However, you can set environment variables in Apache and PHP.

In Apache configuration file:

SetEnv ENV_VAR var_value

Restart, the server. Then you should be able to fetch this variable using $_ENV in PHP.
