# xdebug 3.x
[xdebug]
xdebug.mode = develop,debug                             # replace the xdebug2 xdebug.remote_enable
xdebug.client_host = host.docker.internal               # IDE machine ip
xdebug.client_port = 9003                               # IDE debug extension TCP port
xdebug.start_with_request = yes                         # replace the xdebug2 xdebug.remote_autostart
xdebug.idekey = "PHPSTORM"
xdebug.remote_log = /var/log/xdebug.log
```
