Tracy VS xDebug

You'll also notice in the corner you have a handy debug toolbar with some custom Flight panels to help you understand what's going on in your application. If you hover over the various items in the toolbar, you'll see a variety of hovers that you can click on to keep sticky on the page (more on that later).

are you logging all errors/warnings and notices in php? and if so , are any coming up? maybe it would be worth adding tracy to your project to display issues? (https://tracy.nette.org)

You may have already used some of Nette's tools in other projects you've worked on and not known it! There is the very extendable Tracy for debugging similar to Whoosh, and Latte for intuitive HTML templating.

I thought to myself, "Wouldn't it be clever if we could have an Xdebug-like step debugger for the evaluation engine? I know that Symfony Console has all the functionality I need for this..."

XDebug is an indispensable debugging tool in PHP development, offering powerful features for breakpoint debugging, performance analysis, and code coverage. With XDebug, developers can set breakpoints in the code, inspect variable values, trace function call stacks, analyze performance bottlenecks, and greatly enhance PHP development efficiency and code quality.

WP Setup has been updated to version 1.1.0, introducing Xdebug support and allowing for easy generation of test coverage reports.

Code profiling: Code profiling involves measuring the performance of your code by analyzing the execution time and memory usage of specific functions or methods. You can use a tool like Xdebug or Blackfire to perform code profiling on your Laravel application. To use Blackfire, ensure that your environment meets the following requirements:

xDebug is a powerful PHP debugging and profiling tool. Integrated with many IDEs, it can be used for step-by-step debugging, setting breakpoints, and real-time value inspection, making the debugging process more efficient. (xDebug is already built into ServBay, no need for separate installation)

It is necessaire to active Xdebug on your PHP. More details on Xdebug official documentation.

Is a Docker WordPress Environment focused on the development of WordPress plugins and themes, supports WP-CLI, phpMyAdmin, Xdebug and WordPress Coding Standards - WPCS.

I've gotten a lot of mileage out of Psalm, a static analysis tool that can help you identify potential bugs and things that might not be considered best practice, and XDebug, a debugging and profiling extension for PHP.
