Can't trigger Xdebug break in PhpStorm using Laravel on Nginx

Question

I have been trying unsuccessfully to get Xdebug to work with Laravel running on php8.0-fpm on nginx.

I am using PhpStorm to trigger the breakpoints, but it seems that even xdebug_break() is not triggered.

These are all the configurations I have, and I can also post phpinfo() in a comment if needed:

nginx:

server {
    listen 80;
    server_name dashboard.local;
    root /var/www/dashboard/public;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options "nosniff";

    index index.php;

    charset utf-8;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    error_page 404 /index.php;

    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php/php8.0-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~ /\.(?!well-known).* {
        deny all;
    }
}

Thank you :)

Edit 1:

I've downgraded to php 7.4 and Xdebug 2.9.8, but it seems I still cannot get any response from Xdebug. As per what LazyOne has asked for, here's all the configurations I have.

xdebug section from phpinfo():

xdebug log:

empty

PHPStorm config:

You are using XDEBUG 3 and the old parameters. Suggest you check out the upgrade guide I spent all afternoon doing the same — RiggsFolly

You have Xdebug v3 .. but keep using Xdebug v2 config parameters. Please go through xdebug.org/docs/upgrade_guide and adjust your settings. Xdebug v3 uses DIFFERENT config params than Xdebug v2. — LazyOne

"but it seems that even xdebug_break() is not triggered." BTW -- this function now works a bit differently than in Xdebug v2 -- it no longer initiates a fresh debug session, it now only works as programmatic breakpoint and nothing more. — LazyOne

Thanks for the help, I've tried using the parameters described in the upgrade guide, but I still can't make it work. If I won't figure it out I'll just downgrade to v2. — VladMB

@VladMB Show what you have got now: 1) what config you are trying to use (php.ini), 2) what the actual/live config is (Xdebug section from phpinfo() output or xdebug_info() captured the same way as you are trying to debug. 3) What Xdebug log has to say about it 4) what PhpStorm config is. Xdebug 3 works just fine here, in both 2020.2.4 as well as 2020.3 RC — LazyOne

After a session with LazyOne we figured that I was not using the proper mode for Xdebug, as I needed to set it to debug. Previously I had it set to develop which meant Development Aids, thinking it encompassed the Step Debugger as well.

This is how the final config ended up looking (for Xdebug 3.0.1):

zend_extension=xdebug.so
xdebug.mode=develop,debug
xdebug.client_port=9009
xdebug.client_host=127.0.0.1

This then made it able for me to trigger breakpoints, provided I had the Xdebug Helper extension in chrome, or gave the XDEBUG_SESSION_START parameter (in my case = to PHPSTORM) when making a request.

Thank you again for the help, LazyOne!
