Preamble
After many hours, I have been unable to get NetBeans to connect to xdebug. Some months ago, after upgrading from an old version of MAMP to MAMP
it works for me now. I have LAMP installed. I modified according to all answers from above, started apache2 and now it flies... i am happy... for some time i thought to switch to phpstorm, but I reconsidered... tweak a little more... et voila. it's working.
Here what I have in php.ini
zend_extension = /usr/lib/php5/20121212/xdebug.so
xdebug.max_nesting_level = 250
xdebug.auto_trace=On
xdebug.remote_enable=On
xdebug.remote_port=9001
xdebug.remote_handler=dbgp
xdebug.remote_host=localhost
xdebug.remote_log="/var/log/xdebug.log"
xdebug.trace_output_dir=/var/www/AMRO
xdebug.idekey="netbeans-xdebug"
