UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support Switching "register_globals" to "Off" for a directory

Is this really all I need to do (?):

1. Create a .htaccess file in the ubbthreads directory.

2. Inside it put the following code:
<IfModule mod_php4.c>
php_value register_globals 0
</IfModule>

-or- <IfModule mod_php5.c> for PHP5

Is that it? Also, is a reboot needed?
