Here's a link to a sample php.ini file to include in your directories. It needs to be in the directory where the php file resides, from what I understand. My host uses cgi and after a lot of looking around I found this. IT did work for me and the changes showed after adding it to al my directories. It is NOT like an htaccess file where the file passes it's values down to the underlying directories. If you use this sample file you will still have to make the changes that gijoe suggests in the file e.g. register_globals is set to ON in this file. This just gives the format.
