HostNed allows you to override php.ini settings to your preference with an .htaccess file. For example, if on a linux server, the global setting for register_globals is On and you have a script that recommends it be set to Off, here's how to change it:
1) In the http root of your web space, see if there is already a file there named ".htaccess". If not, create one.
2) Edit the file and add the following line somewhere on it's own line.
php_flag register_globals off
3) Exit and save the file.
You have now set register_globals to off for your entire domain. Easy!
Very helpful, thanks.
