It will revert once the session is complete. Running this export command will create an environment variable for the current terminal session. This variable flag will inform the Xdebug listener that the script is running. Terminal Create an environment variable for XDEBUG_CONFIG and set the value to 'idekey=VSCODE'. You should now see a step toolbar with the blue arrow buttons greyed out: This doesn't actually start the debugging process, but it starts a listener that will be triggered once you run the PHPUnit test. Start Debugging by clicking on the green arrow button. Open a PHPUnit test file and set a breakpoint using the debugger plugin. There is no need to modify the default launch.json file. Click on the "config" button (the cogwheel) and select PHP. If you're using PHP 7.1, you can run:įor CLI Remote Debugging, these are all the configuration settings we need in the ext-xdebug.ini file. Install the Xdebug PHP Extension.įor MacOS users, you can easily install the Xdebug extension for your version of PHP using Homebrew. These steps assume that you are running tests on the same machine that you are editing with. We will need to configure the Xdebug PHP Extension, Visual Studio Code, and your Terminal for this to work. If you're using Laravel Homestead to develop locally, you may want to read this post to get started. After many hours of stumbling around, I found the configuration that works to use Xdebug Remote Debugging with one of the more popular editors out today, Visual Studio Code. However, I want to use it in the terminal by running PHPUnit tests. You can trigger Remote Debugging in two ways:Īlmost all of the resources I have come across for using Xdebug cover the first use case, via the browser. (You can read about all of the Xdebug features here.) In this post, though, I'm focusing on one specific feature called Remote Debugging (a misleading name since we can debug just fine without a remote system). xdebug.modedebug xdebug.startwithrequestyes xdebug.discoverclienthosttrue xdebug.remotecookieexpiretime 3600 xdebug.clienthostlocalhost xdebug.clientport 9003 xdebug.idekeyVSCODE 11 leavasco, Bug-Storm, officialsuyogdixit, AMCASTRO-InsudPharma, githubpendosoft, clapas, diadras, QuenanChever, Nick-Hope, mkendallmcintosh. or alike as temp paths on Ubuntu are virtualized per app/process), try to. Xdebug is incredibly powerful and has many underutilized features. 1) Show whole Xdebug section of your phpinfo () output (or xdebuginfo () captured in the same way as you are trying to debug (a web page or a CLI - its important) 2) Enable Xdebug log (do not point it into tmp folder, use something like /var/log/. Why don't more developers use Xdebug in their development workflow?įrom my experience, many developers don't fully understand the Xdebug architecture and its use cases. I am usually enlightened with the inner workings of Laravel, which is an added benefit. copying the xdebug config lines from the /etc/php5/apache2/php.ini file into /etc/php5/cli/php.ini. On Windows, you may create in your PATH dir a phpp.cmd file, containing php -d xdebug.profilerenableOn then you can simply run phpp .The cost and time savings add up quickly! There have also been occasions where, in the process of stepping through client code, I find myself in Laravel's core code. That always stores the debug output in your current working directory. Using Xdebug, I can step through code while watching values change without having to add a single dd() entry and without the need to run the tests multiple times. However, there are instances where a real debugging setup can improve my efficiency tenfold. Except now, with a bruised ego.Äon't get me wrong, dd() is a wonderful tool that I will continue to use. Hours later, I end up closing my open browser tabs and going back to littering my codebase with dd(). I think to myself, "There has to be a better way." The next thing I know, I'm researching Xdebug blog posts, reading the documentation, and getting frustrated that I still can't get it to work. The process usually begins with me noticing how often I've been using dd() while re-running my PHPUnit tests. & echo "deb stable main" > /etc/apt//yarn.I've lost track of how many hours I have spent trying to configure and use Xdebug. RUN apt-get update & apt-get install -y \ RUN chmod +x /usr/local/bin/install-php-extensions & \ In that case, Xdebug will trigger if the supplied value matches any of. From Xdebug 3.1, it is possible to configure multiple values by using a comma separated list. The IDE Key is only important for use with the DBGp Proxy Tool. docker/mysql:/docker-entrypoint-initdb.d string xdebug.idekey complex Controls which IDE Key Xdebug should pass on to the debugging client or proxy. docker/php/php.ini-development:/usr/local/etc/php/php.ini docker/php/xdebug.ini:/usr/local/etc/php/conf.d/xdebug.ini docker/php/local.ini:/usr/local/etc/php/conf.d/local.ini XDEBUG_MODE is being read correctly though. When I output xdebug_info() it says "no value" for xdebug.idekey. I have a docker-compose file that has the XDEBUG_CONFIG environment variable configured, but Xdebug is ignoring it.
