I've just released version 2.0 of Crell/Tukio! Available now from your favorite Packagist.org. Tukio is a feature-complete, easy to use, robust Event Dispatcher for PHP, following PSR-14. It began life as the PSR-14 reference implementation.

Tukio 2.0 is almost a rewrite, given the amount of cleanup that was done. But the final result is a library that is vastly more robust and vastly easier to use than version 1, while still producing near-instant listener lookups.

Some of the major improvements include:

Static methods and properties have a storied and controversial history in PHP. Some love them, some hate them, some love having something to fight about (naturally).

In practice, I find them useful in very narrow situations. They're not common, but they do exist. Today, I want to go over some guidelines on when PHP developers should, and shouldn't, use statics.

In full transparency, I will say that the views expressed here are not universal within the PHP community. They do, however, represent what I believe to be the substantial majority opinion, especially among those who are well-versed in automated testing.

I am pleased to announce that the trio of libraries I built while at TYPO3 have now reached a fully stable release. In particular, Crell/Serde is now the most robust, powerful, and performant serialization library available for PHP today!

Serde is inspired by the Rust library of the same name, and driven almost entirely by PHP Attributes, with entirely pure-function object-oriented code. It's easy to configure, easy to use, and rock solid.

The term "technical debt" gets thrown around a lot. Way too much, in fact. Part of that is because it has become a euphemism for "code I don't like" or "code that predates me." While there are reasons to dislike such code (both good and bad), that's not what the term "technical debt" was invented to refer to.

So what does it mean? There's several different kinds of "problematic code," all of which come from different places.

In the last 2 years or so, I've run into a number of projects that claim to use the PSR-3 logging standard as published by the PHP Framework Interoperability Group (PHP-FIG, or just FIG). Unfortunately, it's quite clear that those responsible for the project have not understood PSR-3 and how it is intended to work. This frustrates me greatly, as PSR-3's design addresses a number of issues that these projects are not benefiting from, and it reduces interoperability between projects (which was the whole point in the first place).

Rather than just rant angrily online (fun as it is, it doesn't actually accomplish anything), many of my PHP community colleagues encouraged me to blog about using PSR-3 properly. So, here we are.

Like much of the world I've been working to migrate off of Twitter to Mastodon and the rest of the Fediverse. Along with a new network is the need for new automation tools, and I've taken this opportunity to scratch my own itch and finally build an auto-posting bot for my own needs. And it is, of course, available as Free Software.

Announcing Mastobot! Your PHP-based Mastodon auto-poster.

At the $dayjob, I am working to have us adopt Lando as a development tool. Lando is a docker-compose abstraction layer that simplifies building standard development environments, such as a bog-standard LAMP stack, and is way easier than raw docker-compose for those cases.

I also wanted to be able to generate test coverage information as part of our Pull Request process. To be clear, test coverage is not the end-all, be-all of good tests, but it is still a useful metric, and can be a useful gate if used properly. Of course, generating test coverage requires running tests; and while most tests should be unit tests that do not require any services, not all are or can be, and many frameworks don't make true unit tests as easy as they should. (cough) So that means building a full dev environment to run tests. There's various tools for that, but I wanted to use GitHub Actions.

PHP 8.2 was released on 8 December, to much fanfare. And, as always, to much wailing and gnashing of teeth about how the PHP language is evolving too quickly and breaking everyone's code. More specifically, it was the earlier, twin announcement that PHP 7.4 reached end-of-life on 28 November, as that has, somehow, forced everyone to suddenly rewrite their entire code base in a hurry.

And... while I sympathize with some of the complaints, I am once again left wondering "how?"

Sorting algorithms are generally old hat to most programmers. They've either analyzed them to death in class, already written many of them, or work in a language where one is provided and they don't need to think about it. Or all three.

For PHP developers, we have a suite of sorting tools available to us: sort(), usort(), ksort(), uasort(), and various other letter combinations. All use Quick Sort internally, which is generally the best performing single-threaded option. Most importantly, many of them let us provide a custom comparison function to use when determining which of two values is larger or smaller.

A while back, I announced the release of my AttributeUtils library and its powerful attribute-based analyzer.

That library was built primarily to support the many edge cases I needed for Crell/Serde, a new, robust serialization/deserialization library built specifically for PHP 8.1.
