php.ini

[PHP]

; Xdebug
xdebug.max_nesting_level = 256
xdebug.show_exception_trace = 0
xdebug.collect_params = 0
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.client_host = ${LANDO_HOST_IP}
; xdebug.log = /tmp/xdebug.log

; Remote settings
xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.remote_host = ${LANDO_HOST_IP}
; xdebug.remote_connect_back = 1
; xdebug.remote_log = /tmp/xdebug_remote.log

Are people using the Xdebug extension for VSCode to debug php? And if so, which one?

I am seeing 3 different extensions in the VSCode extensions marketplace named "PHP Debug" and the description "Debug support for PHP with Xdebug" - I have been trying to use Felix Becker's version because it has the most downloads but I cannot get it to work. (I get an error saying port 9003 is refusing connections but I don't even have my firewall on my mac turned on) At this point I am wondering if the extensions are the problem

@karlkaebnick I do have Xdebug working with Lando and VSCode with this gist's settings.

PHP Debug is the VScode extension I use.

On some system, you have to open the port 9003 for debugging session to work, as follow for instance:

sudo iptables -A INPUT -p tcp -d 0/0 -s 0/0 --dport 9003 -j ACCEPT

See the Known issues on Lando documentation for reference.

Thanks @chrishappy but unless I'm wrong, the same link was already provided in the previous comment.

Ah yes. I didn't realize that link was also to the official guide. Maybe someone else would also be confused?
