Don't forget that we have excellent tooling in #PHP ecosystem! You're not alone with your upgrades, you can use @PHPCSFixer, #Rector, #PHPCodeSniffer with #PHPCompatibility plugin and probably many other tools. Trust me, it's doable 😁.

Please keep in mind that until @thephpf was created #PHP has been under development for free and every change (fix, new feature, improvement) was provided voluntarily. Even with Foundation, a lot of people work on the language and tooling for free.

Every couple of weeks, I find myself checking on #PHPCodeSniffer to see if there's a new release that supports readonly classes in PHP.

It looks like it's now part of the 3.8.0 milestone. Yay! Fingers crossed that's coming soon. 🤞
