Does two php.ini files mean that I installed PHP twice?
===

I'm on Ubuntu 11.10 with lampp installed and working correctly. Since I couldn't install xDebug as PHP module for use in Eclipse I searched a bit and stumbled upon two different php.ini files. One is located in  /etc/php5/cli, and the other one in /opt/lampp/etc.
a call to PHP's phpinfo() says that it loaded config file from /opt/lampp/etc, but when I run "php --ini" it says that loaded one is from /etc/php5/cli. Do I need to uninstall the one from /etc?
