Increase minimum PHP supported version

[Kocal]

IDK what will be the new miminum PHP supported version for UX, but I guess it will depends when it will be released, and depending on Symfony 8.0 too?

For refs:

• PHP releases: https://www.php.net/supported-versions
• Symfony 8.0 https://symfony.com/releases/8.0

I would personnaly say: UX 3.0 should be 8.2 minimum

And we'll see in december for SF 8.0 ?

Given internal discussions, there is about 99.99% change Symfony 8 requires at least PHP 8.4.

But, requiring PHP 8.4 means that we will should remove compatibility with Symfony 6.4 (PHP 8.1) and 7.x (PHP 8.2).

Requiring PHP 8.2 means that we will remove compatibility with Symfony 6.4, which is maintained until November 2026, for 17 months. And I feel wrong about this, since framework-bundle still represents as much installations for 6.x:

To summarize my thoughts, I don't think right now we should increase the minimum supported PHP version, maybe in one/two years, for a 4.x or 5.x?

EDIT: ignore text above 😅 let's say PHP 8.2 for UX 3.x :)

It's totally possible to run a Symfony 6.4 app on PHP 8.4, which means I don't understand this side of the presented argument.

... yes 🤦🏻

I think I'll go to sleep :D
