问题
I've installed Xdebug on Ubuntu serve rand I've set /etc/php/5.6/apache2/conf.d/20-xdegug.ini file this way
zend_extension=xdebug.so
xdebug.remote_host = 192.168.0.140
xdebug.remote_enable = 1
xdebug.remote_port = 9000
xdebug.remote_handler = dbgp
xdebug.remote_mode = req
remote_host is an Ubuntu 16.04 virtual machine on the same local network that my computer.
When I try to start the debugging NetBeans has a message on bottom waiting for connection (netbeans-debug) and the execution doesn't stop on the breakpoint.
I'm using CodeIgniter and the URL is launched with ?XDEBUG_SESSION_START=netbeans-xdebug parameter added to the URL.
I'm not sure about which php.ini I have to modify:
/etc/php/5.6/cli/php.ini
or
/etc/php/5.6/apache2/php.ini
