Xdebug

This is an xdebug client that offers:
- stepping through code,
- setting breakpoints,
- viewing stack backtrace,
- evaluating expressions.

To get started:
1. Install the app.
2. Run it and configure (in-app settings).
3. Click 'Listen' button.
4. Run your code.

Something not working? Try the in-app 'Settings/Help' button.

Still now working? Issues can be reported on the project website.

Thanks!
