Xdebug

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

Configuration and usage

Please follow PhpStorm documentation before actions described below.

PhpStorm basic configuration

1.Check /docker/dev/xdebug-main.ini or /docker/dev/xdebug-osx.ini (optional)

  • Set option in case you need to debug every request to an api (by default):
xdebug.start_with_request = yes
  • Set option in case you need to debug only requests with IDE KEY: PHPSTORM from frontend in your browser:
xdebug.start_with_request = no

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

3.Check your Run/Debug Configurations as on image below:

Basic configuration

Basic configuration

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

Using Xdebug

After actions above, you can start listening for 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 page in the browser

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 need to uncomment/edit (nothing to do in case MacOS and XDEBUG_CONFIG=osx) option xdebug.client_host inside config docker/dev/xdebug-main.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, please follow the next steps:

  1. Enter inside supervisord docker container shell using your local shell command make ssh-supervisord
  2. Inside supervisord container shell run the next command supervisorctl
  3. Stop program messenger-consume:messenger-consume_00 using the 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 the next command exit
  5. Exit from supervisord docker container using command exit. Make sure that you are in the local shell.
  6. Enter inside 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 inside symfony docker container shell the next command 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 turn on the program messenger-consume:messenger-consume_00 (step 1, 2 and execute start messenger-consume:messenger-consume_00) inside supervisord docker container when you'll finish your debugging (or you can simply restart environment using your local shell command make restart).
