Ah yes, the age-old tale: spend two years in #architecture #purgatory, only to find salvation in the open arms of #PHP 😇. Who knew the key to world peace was a language everyone loves to hate? 😂 But hey, why ship features when you can debate the elegance of code forever? 🚀

Traits in #PHP are a limited purpose tool, but they do have a purpose.

Anyone fancy a #PHP challenge that sounds super simple but might actually be impossible?
One page hit, two sessions. That's all I want!
Start a session, save some data, switch to a new session, save some different data, reload the page and be able to switch between both data arrays.
Should be simple, no?
Whatever I do, the session IDs either end up the same and data crosses over, or the second session's ID changes each time so the data doesn't persist.
I've literally spent all day on this 😩

Question aux pros de Kirby CMS : j’ai fait un site avec beaucoup d’images volumineuses qui sont servies « à la bonne taille » par Kirby avec la fonction crop(). Jusque là super, sauf qu'en prod certaines images (pas toutes) ne sont pas prises en compte et je me retrouve avec quelques miniatures de 5333 px de large (et plus de 1 Mo) au lieu des 1000 px demandés, ce qui est évidemment hautement pénalisant.
Des idées sur ce qui se passe ?

#PHP has final const since 8.1 — because apparently a constant wasn't constant enough.

Depending on your expectations, passing an associative array to Eloquent's orWhere method might not do what you think. Here's a real bug I found and the simple fix. #php #laravel https://masteringlaravel.io/daily/2026-02-24-make-sure-you-know-how-orwhere-works-with-multiple-values
