Xdebug

This document describing how you can use Xdebug and PhpStorm within DEV environment.

Configuration and usage

Please follow PhpStorm documentation before actions described bellow.

PhpStorm basic configuration

1.Check /docker/dev/xdebug.ini (optional)

  • In case you need debug only requests with IDE KEY: PHPSTORM from frontend in your browser:
xdebug.start_with_request = no

Install locally in Firefox extension "Xdebug helper" and set in settings IDE KEY: PHPSTORM

  • In case you need debug any request to an api (by default):
xdebug.start_with_request = yes

2.Go to Settings -> Php -> Debug and set Xdebug port 10000

3.Check your Run/Debug Configurations as on image bellow

4.Install needed browser extensions (optional, see step 1). For example for Firefox install extension "Xdebug helper" and set in extension settings IDE KEY: PHPSTORM

Basic configuration

Using Xdebug

After actions above you can start to listen incoming PHP debug connections:

  1. Add breakpoint to your code
  2. Enable Xdebug in your browser (optional, required only when xdebug.start_with_request = no)
  3. Click Debug button in PhpStorm
  4. Reload browser page

If everything configured properly you will get something like next:

Using Xdebug

Debug Postman requests

If you're using Postman to test/debug your application when xdebug.start_with_request = no you need to add ?XDEBUG_SESSION_START=PHPSTORM to each URL that you use with Postman. If you have default configuration (xdebug.start_with_request = yes) - nothing to do and your Xdebug should work out of the box.

Debug Console commands / Messenger async handlers

If you want to debug console commands or messenger async handlers you just need to uncomment/edit option xdebug.client_host in config docker/dev/xdebug.ini:

xdebug.client_host=172.17.0.1

Just find out the proper host ip in your docker bridge configuration and set above option (in general it is 172.17.0.1). Don't forget to rebuild docker containers according to general documentation.

If you want to debug your messenger async jobs just follow next steps:

  1. Enter in supervisord docker container shell using your local shell command make ssh-supervisord
  2. In supervisord container shell run next command supervisorctl
  3. Stop program messenger-consume:messenger-consume_00 using next command stop messenger-consume:messenger-consume_00 and make sure that you can see message messenger-consume:messenger-consume_00: stopped
  4. Exit from supervisorctl shell using next command exit
  5. Exit from supervisord docker container using command exit. Make sure that you are in local shell.
  6. Enter in symfony docker container shell using your local shell command make ssh
  7. Put necessary message in queue or make sure that it is already there
  8. Run PHPStorm debug
  9. Run in symfony docker container shell next command in order to run your async handlers /usr/local/bin/php bin/console messenger:consume async_priority_high async_priority_low --limit=1 (where limit option is a number of messages that you want to debug)
  10. Have fun with debugging and don't forget to switch on program messenger-consume:messenger-consume_00 (step 1, 2 and execute start messenger-consume:messenger-consume_00) in supervisord docker container when you'll finish your debugging (or you can simply restart environment using your local shell command make restart).
