[PHP 7.4] Versioning of ext-json

[carusogabriel]

Up to PHP 7.3, the json extension used to follow its own versioning.

Now, in PHP 7.4+, it is following the same as other extensions: PHP's version number:

• json: https://3v4l.org/1NjFH
• reflection: https://3v4l.org/ca9vS

For reference: php/php-src#4459

@lcobucci How can we solve this? Adding || ^7.4 or replacing it with * when declaring ext-json in the requirements of Composer?

[lcobucci]

I think that having ^1.7 || ^7.4 for ext-json makes more sense than *.
With that, we should solve PHP 7.4 compatibility and be able to disallow failures for 7.4snapshot.

For v2.2 we should just require PHP 7.4+ IMHO.

Does this make sense to you?

[carusogabriel]

@lcobucci Yeah, it does 👍

I'll open the PR.

I'd recommend always specifying builtin extensions as *, because these are always tightly bound to the PHP version. You need to change the PHP version requirement as a whole if you want to change a builtin extension requirement.

[lcobucci]

That's a good point @nikic. I'm fine with * for builtin extensions 👍
