Using a vector database with PHP PHP has roughly 80 array functions: eight – zero. array_map, array_walk, array_reduce,array_filter, array_each… wait, that last one was deprecated and removed in PHP 7.2.

Types and Tests: Not Rivals, Just Working Different Shifts A common source of confusion in PHP development is the relationship between static analysis and unit testing. Are they redundant?

php-typos: A Fast Spellchecker for PHP Codebases (Tool Review) There’s a particular kind of embarrassment reserved for the typo that ships to production. A recievePayment() method. A config key spelled treshold. A comment that confidently explains the “lenght” of an array. None of it breaks anything, all of it makes the codebase look a little […]

Putting PHP’s M_EULER to Work PHP ships with more mathematical constants than most developers ever use. One of the most overlooked is M_EULER, which is the Euler constant.

And yet, when a new developer tool ships — a security scanner, an AI code assistant, a code counter, a refactoring engine: PHP support is often an afterthought, a footnote, or simply missing.

The turbofish meet the elephpant: 🐟 Somewhere, probably on an infinite step of grass, the turbofish meets the elephpant. You’ll need imagination to picture that, for sure, but by November, you’ll probably have it in your reality. So, what is this new fish, and what does it have to do with generic types? Let’s take […]

Filtering Empty Arrays Before array_merge()? Picture this: you’re looping through something, calling a function each time. It always returns an array, and, sometimes it gives back an empty array. At the end, all these array will be array_merge(…$results) together. The first point is to avoid array_merge() inside the loop, as it is one of the […]

That’s what this post is about: testing regex with reverse generation using pointybeard/reverse-regex to generate strings guaranteed to match a regex, so you can test your validation code against inputs you didn’t […]

The Empty String in PHP: One Value, Too Many Jobs The humble empty string “” is everywhere. It’s the quiet default, the silent failure signal or the silent success signal, the lazy cast, the natural accumulator. Behind the obvious simplicity of the empty string in PHP lies a surprising amount of overloaded meanings, which leads […]
