The .htaccess file is pretty handy as it can also allow you to set various PHP flags that you may not want enable for all of you websites and in turn will let you run just about every PHP flag or directive on a one on one website basis.
The format of the .htaccess is simple, however you will want to comment out exactly what flag or directive you are enabling for the site. An example of this would be as seen below :
#Turn register goabls of
php_value register_globals off
#Php max upload size
php_value upload_max_filesize 12M
php_value post_max_size 12M
Make sure you save the file when you are done editing it.
Just about any directive or flag can be added to the .htaccess file so you can commently customize the php functions of the website instead of changing it globally in the php.ini file. For a list of what you can use, please review the PHP manual at http://php.net/manual/en/index.php.
