SetEnv directives in VirtualHost configuration not accessible in PHP

Hi, I have the following directive in my virtual host configuration: SetEnv APP_CONFIG_SECTION "development" and would like to access the value from PHP with getenv('APP_CONFIG_SECTION') or $_SERVER['APP_CONFIG_SECTION'] or whatever. But none of them work. Is there any PHP / Zend / Apache2 / ... configuration option etc. I have to activate / deactivate in order to use SetEnv? I am using the Debian packate apache / php installation and the current version of the Zend Framework. I tried to use `safe_mode_allowed_env_vars = PHP_, APP_CONFIG_' in php.ini - but this didn't change anything either. mod_env seems to be loaded also: /etc/apache2/mods-enabled/env.load -> ../mods-available/env.load Thanks, Dietrich
