Xdebug Update: March 2022

In this monthly update I explain what happened with Xdebug development in this past month. These are normally published on the first Tuesday on or after the 5th of each month.

Patreon and GitHub supporters will get it earlier, around the first of each month.

You can become a patron or support me through GitHub Sponsors. I am currently 46% towards my $2,500 per month goal. If you are leading a team or company, then it is also possible to support Xdebug through a subscription.

In March, I spend 39 hours on Xdebug, with 25 hours funded.


Most of my time in March was spent on investigating and fixing bugs. Ranging from a crash during debugging of closures with static properties, support for showing ArrayObject elements while debugging, improvements to code coverage, and bugs with Xdebug's step-debugger triggering mechanism.

I also improved Xdebug's diagnostics by adding warnings. I added one for when systemd PrivateTmp directories are used. And Xdebug now also warns if zlib compression is enabled in situations, such as with the profiler's append feature, where it can not be used.

I spend a considerable amount of time cataloguing the different set-ups that developers use, and how to configure Xdebug's debugger. This work will result in better documentation and perhaps a flow chart. The research is also useful for the Xdebug Course that I have mentioned before.

I have not figured out how to do it will all different set-ups, so if you have extra information, or if I am still missing set-ups, feel free to comment on the Google Doc.

In the more complicated set-ups, perhaps it would be easier to use Xdebug Cloud as it has none of these networking complications.

Xdebug Recorder

I have been making steady progress with a first version, which can now play back recording information and display it in the likeness of an Xdebug trace file. There are still a few bugs outstanding, and I also have not added support for objects yet.

I will be recording a video with a demo once I have something to show. You can follow the development in the recorder branch.

Xdebug Cloud

Xdebug Cloud is the Proxy As A Service platform to allow for debugging in more scenarios, where it is hard, or impossible, to have Xdebug make a connection to the IDE. It is continuing to operate as Beta release. Packages start at £49/month.

If you want to be kept up to date with Xdebug Cloud, please sign up to the mailinglist, which I will use to send out an update not more than once a month.

Xdebug Videos

I have published no new videos this month. You can find the existing ones on my YouTube channel.

Business Supporter Scheme and Funding

In March, no new business supporters signed up.

If you, or your company, would also like to support Xdebug, head over to the support page!

Besides business support, I also maintain a Patreon page and a profile on GitHub sponsors.
