Unable to get Xdebug 3 working with Laravel Sail, Docker and Visual Studio Code

Question

I've spent hours and hours trying everything I or Google could think of, but Xdebug doesn't stop on any breakpoints.

Also had a look at this question and answers but still... no luck: Unable to get Xdebug 3 working with Docker

In the past it worked, but somehow it stopped working. Maybe an update of docker or whatever package / app caused it to stop.

On macOS:

• deleted docker, reinstalled it with the newest version (4.8.1 78998).

• removed my current Laravel Sail project and created a new Laravel Sail project through curl -s "https://laravel.build/example-app" | bashcurl -s "https://laravel.build/example-app" | bash

• added SAIL_XDEBUG_MODE=develop,debug to the newly created.env file

• sail up -d to start everything

• removed and reinstalled Visual Studio Code newest version: 1.6.7.1

• created a PHP launch.json file with the following contents:

   { "version": "0.2.0", "configurations": [ { "name": "Listen for Sail Xdebug", "type": "php", "request": "launch", "port": 9003, "pathMappings": { "/var/www/html": "${workspaceFolder}" }, "hostname": "localhost", "ignore": [ "**/vendor/**/*.php" ], "xdebugSettings": { "max_data": 65536, "show_hidden": 1, "max_children": 100, "max_depth": 3 } } ] }

• got the following message inside of VSCode:

  'Cannot validate since a PHP installation could not be found. Use the setting 'php.validate.executablePath' to configure the PHP executable.'

  I don't know if this is the problem or what I should do since I'm using docker.

• placed a breakpoint in the route file or whatever else file that you create

• inside of the 'Run and Debug' tab of VSCode I told it to use config 'Listen for Sail Xdebug' and run the debugger (F5) -> I checked all checkboxes for breakpoints (notices, warnings, errors...)

Nothing happens. VSCode does not stop on any breakpoint.

I still have no idea where to look as to get it working again.

I would be very happy if someone, maybe Derick himself, could help me out here. The last hairs that I still have are about to pulled out:O

Please let me know if you need any more information, settings or code from me!

Answer 1

Laravel Sail should work straight out of the box. I have made a 5 minute video titled "Laravel Sail with PhpStorm", but it should work equally well with VS Code with the configuration that you outlined.

To find out why something does not work, you can either try debugging a file that has xdebug_info() in it. It will tell you whether (and if) Xdebug tried making a connection, to where, and what the result was. There are also links to the documentation directly next to each error message (if present).

Your log says:

Diagnostic Log No messages

Which means that you did not instruct Xdebug to start a debugging session through a trigger. You need to tell Xdebug to start one. The Laravel Sail documentation points to the Xdebug documentation on how to do this. It recommends you use one of the mentioned browser extensions to "click" when you want to debug or not.

If you need more debugging information, make a log file and crank it up to 10: xdebug.log=/tmp/xdebug.log and xdebug.log_level=10 .

Answer 2

I had the same problem as you trying to get Laravel Sail, XDebug and VS Code to cooperate for debugging on a newly created Laravel project on Linux although it should work as it is with just adding SAIL_XDEBUG_MODE=develop,debug in the .env file. It didn't work until I also added SAIL_XDEBUG_CONFIG="client_host=localhost" in the .env file. I didn't have to change anything in the default launch.json that was created automatically from VS Code. Just remember to restart VS Code to lauch the docker containers with the new configuration.

I had the same problem. I have fixed this issue by updating php.ini file of docker. To update php.ini of you sail docker you have to follow this steps

1. run:

./vender/bin/sail artisan sail:publish

This will create docker folder in root of your project.

2. update php.ini of docker/8.1 folder. Add this code in php.ini

---

 [XDebug] zend_extension = xdebug.so xdebug.mode = debug xdebug.start_with_request = yes xdebug.discover_client_host = true xdebug.idekey = VSC xdebug.client_host = host.docker.internal xdebug.client_port = 9003

3. Refresh sail docker container with:

   ./vender/bin/sail build --no-cache

4. run docker and enjoy your xdebug with vscode.
