These directives have only effect when safe-mode itself is enabled!

safe_mode_allowed_env_vars string

Setting certain environment variables may be a potential security breach. This directive contains a comma-delimited list of prefixes. In Safe Mode, the user may only alter environment variables whose names begin with the prefixes supplied here. By default, users will only be able to set environment variables that begin with PHP_ (e.g. PHP_FOO=BAR).

Note: If this directive is empty, PHP will let the user modify ANY environment variable!
safe_mode_protected_env_vars string

This directive contains a comma-delimited list of environment variables that the end user won't be able to change using putenv(). These variables will be protected even if safe_mode_allowed_env_vars is set to allow to change them.
