A simple comment on a function name led to a much bigger refactoring. Here's why I've learned to welcome code review feedback instead of resisting it. #php #laravel https://masteringlaravel.io/daily/2026-02-04-republished-dont-get-defensive-during-code-review

Wondering how many APIs implementing standards defined via #openapi specs are validating payload accidentally wrong as the tooling doesn't take into account that pattern fields contain ECMA based regular expression bodies while the spec implementors use PCRE2 or other regex engines available in their programming languages.
Subtle differences in syntax leading to wrong escaping leading to ranges of characters being duplicate singular matches. Or implementations based on different unicode versions etc.
Luckily specs often might have plain and simple regex patterns. Doesn't help when character classes like \w are maybe interpreted as unicode letters and numbers in PCRE2 (/u) while #JavaScript means [A-Za-z0-9_] or whatever other constellations are thinkable. And I don't even understand utf16/utf8 subtleties with surrogate pairs or whatnot.
Fun. I should implement something to help with this in #php. Libs don't seem to take this into account if my understanding is correct.

@toflar presenting #loupe, a search engine build on top of SQLite written in PHP.
Great walkthrough on how Information Retrieval systems implemented their storage layers, and their ways to optimize query and matching algorithms.
A huge work on research and implementation, great job Yanick!

Spend two hours on learning how to update the German #php docs #translation and making my first two PRs:
https://github.com/php/doc-de/pull/210
https://github.com/php/doc-de/pull/211
If you ever wanted to learn how to contribute to the translation, but felt it wasn't clear on how to do it:
Feel free to reach out, happy to help you get going.
