Php – XDebug setup in the VS Code

I’m new to xdebug world and therefore setup below is mostly copied from tutorials. Unfortunately, the PHP debugging doesn’t start to work. Don’t stop on breakpoint. I don’t understand what is missing.

My setup:
VS Code machine: 192.168.1.220

Dev website (site is fully functional):
Address locally: 192.168.1.182:8100 or http://myNasServer:8100,
Public phpinfo (reverse proxy " Nginx Proxy Manager"): https://intranet.adplus.ee/info.php
The website runs in a docker container and is using PHP 5.6.40 (it is an old app and requires this php)

Docker-compose file:

version: '2.2'

services:
  db:
    image: mysql:5.7
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: my_secret_pw_shh
      MYSQL_DATABASE: test_db
      MYSQL_USER: devuser
      MYSQL_PASSWORD: devpass
    ports:
      - "9906:3306"
    volumes:
      - ./dbdata:/var/lib/mysql
    command: --sql_mode=""
  web:
    container_name: php_web
    build:
        context: ./php
        dockerfile: Dockerfile
    depends_on:
      - db
    volumes:
      - ./php/intra/:/var/www/html/
      - ./php/local.ini:/usr/local/etc/php/conf.d/local.ini
    ports:
      - "8100:80"
    stdin_open: true
    tty: true

XDEBUG config in local.ini file (Netbeans suggested configuration)

[xdebug]
zend_extension="xdebug.so"
xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_port=9003
xdebug.idekey="netbeans-xdebug"
xdebug.remote_log="./xdebug.log"
xdebug.show_exception_trace=1

Vs Code launch configuration

"version": "0.2.0",
    "configurations": [
        {
            "name": "Listen for Xdebug",
            "type": "php",
            "request": "launch",
            "port": 9003,
            "pathMappings": {
                "/var/www/html/": "${workspaceFolder}"
            },
            "log": true           
        },
        {
            "name": "Lauch currently open script",
            "type": "php",
            "request": "launch",
            "program": "${file}",
            "cwd": "${fileDirname}",
            "port": 9003,
        }
    ]
}

    Your Xdebug configuration uses everything for Xdebug 2, and not 3, which you’re most likely using. You need a newer tutorial, or read the upgrade guide.

    I would also suggest you read the official documentation, right on Xdebug’s website: https://xdebug.org/docs/step_debug — which also links to a 5 minute video on how to do it with Docker: https://www.youtube.com/watch?v=ZIGdBSD6zvU

    From what you written I understand you run your VS Code IDE and your PHP on different machines. Since you mention myNasServer I suspect you have your PHP files mapped via SMB or NFS to your local workstation.
    Since Xdebug connects to the IDE you need to tell it either with xdebug.remote_host=192.168.1.220 or enable xdebug.remote_connect_back=1.

    Although from the log you posted it seems that Xdebug is indeed trying to connect, you can also try to add xdebug.remote_autostart=1 that will start debugger regardless of the trigger cookie/get parameters.

    Also, I want to extend my heartfelt sympathy for you needing to work on a PHP5 application… 🙂
