Where is php config and .htaccess located on Raspbian?

I am trying to change the upload limit of my owncloud installation. A raspberry pi and the Raspbian OS are powering this server. Apparently I can edit the php config or the .htaccess config but I am unsure of where either of those are located. It says .htaccess is located inside the owncloud install directory. And the php config is here /etc/php5/apache2/php.ini . But when I use nano to edit the php config it's blank. I am pretty sure it exists somewhere because My owncloud installation is working and I can upload small files. Anyone got any suggestions?
