Hi, xdebug works for me with Netbeans 11.1.
My configuration is:
Netbeans (Tools->Options->PHP->Debugging):
Debugger port: 9000
Session ID: netbeans-xdebug
Maximum data length: 2048
All remaining checkboxes are unchecked.
xdebug.ini (/etc/php/7.3/apache2/conf.d/20-xdebug.ini):
zend_extension=xdebug.so
xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_host=localhost
xdebug.remote_mode=req
xdebug.remote_port=9000
xdebug.show_local_vars=on
;xdebug.force_display_errors=1
;xdebug.force_error_reporting = E_ALL
;xdebug.show_exception_trace=1
xdebug.var_display_max_children = 16
xdebug.var_display_max_data = 4096
xdebug.var_display_max_depth = 16
A few notes:
1. You may have multiple xdebug.ini in your system, make sure you edit the right one (normally there is at least one for CLI and another for Apache2).
2. in remote_host you can try to replace localhost with 127.0.0.1
3. Don't forget to restart the relevant server (i.e. apache) after editing.
Regards,
Paolo
