I installed Mint 16 Petra 64bit. I would sincerely like to help others avoid all the problems below.
My first mistake was to install Apache2 from Software manager + associated packages.
I installed Aptana Studio 3 which I use for Pydev on Windows. Aptana would not enable PHP debugging successfully, so I tried Eclipse.
Eclispe and Aptana have similar interfaces which I found inscrutable.
After trying to get a PHP debugger working, by uninstalling some extras, I had to do a full install of Mint 16.
On the new Mint install I installed Xampp. At least I only had one HTTP server on 80.
I tried Eclipse and Aptana again, but debugger would not work.
I have spent 28 hours on all this.
After some searching I found NetBeans, and was working within 2 hours.

Then in php.ini I added
[zend]
zend_extension=/opt/lampp/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
