In order for these settings to work in your htaccess file, you will need to add "Options" to your AllowOverride specifications for the directory/webserver if it's not already allowed.

PHP_INI_SYSTEM can be configured per-directory by placing it inside a per-directory block in httpd.conf.
# Selectively enable APC for wildly popular directories
# apc.enabled is Off in php.ini to reduce memory use
<Directory /usr/local/apache2/htdocs/forum>
php_flag apc.enabled On
</Directory>

In .htaccess, only true/false on/off flags can be set using php_flag. To set other values you need to use php_value, like this:
php_value upload_max_filesize 20M
