Fun fact: The world’s first computer bug was a real moth! But don’t worry, we’re not here to debug insects. We all know that debugging is vital in website development. It helps developers identify and resolve issues, leading to a smoother and more reliable end product. To achieve that, you need the right tools. One such technique that can help you troubleshoot your PHP is XDebug.In this article, I’d like to share the steps and requirements involved in setting up PHP debugging with XDebug on Lando and DDEV Drupal setups using the VS Code IDE. Let’s dive in!

What is XDebug
Xdebug is a standard and powerful debugger in PHP and improves your development experience. It provides us developers with key features that help in finding and fixing the errors in code. 
Step Debugging – A way to step through your code in your editor while the script is executing.
Improvements to PHP’s error reporting – This allows you to get better error messages and obtain more information from PHP’s built-in functions. An upgraded var_dump() function, stack traces for Notices, Warnings, Errors, and Exceptions to highlight the code path to the error.
Tracing – When an error occurs, Xdebug generates detailed stack traces that show the sequence of function calls leading up to the error, helping developers pinpoint the source of the issue. Xdebug helps in tracking the values of variables during script execution, making it easier to understand how values change as the script progresses.
Profiling – With the help of visualization tools, it allows you to analyze the performance of your PHP application and identify bottlenecks. 
Code Coverage Analysis – This can generate code coverage reports, to show which parts of your code base are executed when running unit tests with PHPUnit.
Support for Various IDEs – Xdebug supports integration with multiple IDEs such as PhpStorm, Visual Studio Code, Eclipse, NetBeans, and more.
XDebug with VS Code IDE
I chose VS Code here as it’s one of the most used and my favorite editor. Install Visual Studio Code (VS Code) if you haven’t already.To make Xdebug work on this IDE, the first thing you need is the ‘PHP Debug’ Extension. Find and install it. This is needed for projects running on Lando or even with DDEV.

PHP Debug Extension
XDebug + VS Code + Lando
Enabling Xdebug on Lando
Lando by default does not provide you with an Xdebug extension. To enable Xdebug on Lando add the xdebug: true line to your .lando.yml file under the config key:
name: TechX
recipe: drupal10
config:
xdebug: trueOr else, override your php service, by adding xdebug: true under appserver:
name: TechX
services:
appserver:
webroot: web
xdebug: trueFollow it up by rebuilding your environment:
lando rebuild -yThis will enable the extension by default whenever you start the Lando environment and Xdebug is now ready to receive the connections.
In terms of performance, an even better option is to toggle between Xdebug on and off with some custom tooling commands.  If you’re using Apache, tweak your .lando.yml with the following lines and don’t forget to run lando rebuild -y after.
config:
# Set Xdebug off by default. We use the tooling below to turn it on as needed.
xdebug: false
services:
appserver:
overrides:
environment:
XDEBUG_MODE: ‘debug,develop’
tooling:
xdebug-on:
service: appserver
description: Enable Xdebug.
user: root
cmd:
– docker-php-ext-enable xdebug && kill -USR2 $(pgrep -o php-fpm) > /dev/null || /etc/init.d/apache2 reload
– tput setaf 2 && echo “Xdebug On” && tput sgr 0 && echo
xdebug-off:
service: appserver
description: Disable Xdebug.
user: root
cmd:
– rm /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini && kill -USR2 $(pgrep -o php-fpm) > /dev/null || /etc/init.d/apache2 reload
– tput setaf 1 && echo “Xdebug Off” && tput sgr 0 && echoNow you can enable and disable Xdebug with custom commands lando xdebug-on and lando xdebug-off.
Browser Requirements
For your browser, install the suitable Xdebug helper extension. On Chrome browsers, enable the Xdebug helper extension.

Xdebug helper – Chrome Extension
If you are using Firefox, try the Xdebug Helper add-on. 

Xdebug helper – Firefox Add-On
Making Xdebug work on VS Code
The next step is to create a custom .vscode/launch.json file within your workspace. This will map paths so that XDebug works correctly.Open your project in the VS Code IDE, go to ‘Run and Debug’ and click on ‘create a launch.json file’ 

Create launch.json file
This will create the launch.json file with relevant configurations. Update the ‘Listen for Xdebug’ section with the below details. Note that the Xdebug 3 listens on port 9003.
{
“version”: “0.2.0”,
“configurations”: [
{
“name”: “Listen for XDebug”,
“type”: “php”,
“request”: “launch”,
“port”: 9003,
“pathMappings”: {
“/app/”: “${workspaceFolder}/”,
}
}
]
}Start debugging!
Add a debug breakpoint to a line in your PHP code wherever you need it by clicking the line number.

Set breakpoints
Enable Xdebug on Lando using:
lando xdebug-onIn the menu, click on Run → Start Debugging. Ensure “Listen for Xdebug” is selected by the green arrowhead at the top left. The bottom pane of VS Code will be changed to orange (live) and should say “Listen for Xdebug”. 

Start Debugging

Start Debugging
In your browser, navigate to your Lando app’s URL and find the Xdebug helper extension in the address bar.  It is usually a “beetle” icon. Click on it and choose “Debug” from the menu to tell your browser to send the appropriate parameters to Xdebug so that Xdebug activates when a request is made. 

Enable Xdebug helper extension
Refresh the page or click on your site link. VS Code should now automatically open the Debug window and produce a debug output if a breakpoint is reached. 

Xdebug in action
Debugging Process
When your code execution reaches a breakpoint, the debugger will stop, and you can inspect variables, step through code, and understand the flow. VS Code will provide a user interface for interacting with the debugging session.
XDebug + VS Code + DDEV
Unlike Lando, with DDEV, Xdebug already exits out of the box. You don’t need any custom service, no rebuild, no browser extensions, no Drama! :)Just update the project’s .vscode/launch.json to add the “Listen for Xdebug” configuration from the below-attached config snippet.

{
“version”: “0.2.0”,
“configurations”: [
{
“name”: “Listen for XDebug”,
“type”: “php”,
“request”: “launch”,
“hostname”: “0.0.0.0”,
“port”: 9003,
“pathMappings”: {
“/var/www/html”: “${workspaceFolder}/”,
}
}
]
}Set a breakpoint in your PDP code. Restart it, if the breakpoint you set isn’t solid red. In the menu, choose Run → Start Debugging and ensure “Listen for Xdebug” is selected. Enable Xdebug on DDEV using:

ddev xdebug onIn a browser, visit your project, and just like you saw earlier, you will be redirected to your IDE once you hit the breakpoint.

Visit the page

Will be redirected to the IDE and stop at the first breakpoint

With the release of Windows 10 21H2, Windows offers inbox support for Mopria compliant printer devices over network and USB interfaces via the Microsoft IPP Class Driver. This removes the need for print device manufacturers to provide their own installers, drivers, utilities, and so on.  Device experience customization is now available via the Print Support Apps that are distributed and automatically installed via the Windows Store. This framework improves reliability and performance by moving customization from the Win32 framework to the UWP software development framework. Finally, print device manufacturers no longer have to rebuild their software since this solution is supported across all Windows versions and editions. With these advancements in the Windows print platform, we are announcing the end of servicing of the legacy v3 and v4 Windows printer drivers. As this is an impactful change, end of servicing will be staged over multiple years. Printer drivers used to be an absolute hell on Windows. Whereas on Linux you just plug the printer in and Linux will find and use the printer without much issue, on Windows, you had to trawl vendor websites using obscure device names and minor version variations just to get the right driver installed – usually accompanied by a whole boatload or crapware. Things got better as Windows eventually started downloading printer drivers and accompanying OEM management software by itself, and it seems this is the next step in the process by moving the functionality from these often crappy printer management applications into Print Support Apps.

Following the launch of the Saloon and the Estate, the All-Terrain rounds off the E-Class family as the third model. Mercedes-Benz has offered the E-Class Estate also as an All-Terrain since 2017.
The E-Class All-Terrain is equipped as standard with AIRMATIC single-chamber air suspension. It provides up to 46 mm more ground clearance and continuously adjustable damping for the compression and rebound stages of the shock absorbers.
Luggage capacity can be expanded from 615 to 1,830 litres. In the plug-in hybrid model, the capacity ranges from 460 to 1,675 litres.
Rear passengers benefit particularly from the 22-millimetre longer wheelbase (2,961 millimetres). They now also have 1,519 millimetres of elbow room – an increase of 25 millimetres.
The E-Class All-Terrain has a braked towing capacity of up to 2,100 kilograms. This also applies to the plug‑in hybrid. The unbraked towing capacity is 750 kilograms. Thanks to a tongue weight of up to 84 kilograms, e-bikes can also go along for the ride.
With the illuminated grille frame (optional), two optical fibre bundles positioned behind the chrome strips receive light from LED modules.
The screen graphics can be customised with two display styles (classic and sport) and three modes (navigation, assistance, service). With the new MBUX, the main display icons are now simpler and colour-coded to resemble smartphone screen tiles.
Depending on the market, the communication module runs on 5G technology. This standard supports much faster data transfer rates than LTE/UMTS.
The digital vehicle key lets drivers use an iPhone or Apple Watch as a car key. After pairing a compatible device paired with the vehicle through Mercedes me connect, the device can be used to start, open and lock the E-Class All-Terrain. Key sharing is also possible. The digital key can be shared with up to 16 persons. In markets where Mercedes me connect services are available, the E-Class All-Terrain can be pre-equipped for the digital key as part of the KEYLESS-GO comfort package.
