@Crell using array for a quick prototyping of a solution is still the fastest way to move forward. Once your domain is "stable" you can then clean up the mess and replace arrays with actual objects. Of course, depending on time and budget constraint you never get the change to reach that stage #PHP I am controversial 🤷
Achievement unlocked: I did some #PHP at work last week.

💻🔥 C’est parti pour les formations #Symfony_Live 2026 !
Une belle énergie dès le premier jour, ravis de vous voir aussi nombreux 👀

Let's be controversial: In modern #PHP, you should never type-hint an array.

I feel that at some point in time I will have to do either write a long post or create a talk around handling #deprecations in #PHP https://github.com/thephpleague/csv/issues/574#issuecomment-4115906017 I regularly get those tickets and conversation and I feel the community does not know what a deprecation is... am I wrong or am I wrong 🤔

I've just been asked to "upgrade" a Perl project, last updated in 2012, to PHP 8
I'm not a #Perl expert
Or a #PHP expert
Current mood:
