Support new PHP 8.3 syntaxes

[jrfnl]

PHP 8.3 includes the following new syntaxes for which it should be verified if the Tokenizer needs updates and/or whether any sniffs need updates:

To Do

• Dynamic class constant fetch - C::{$name}
  • Tokenizer changes needed ?
  • Sniff updates needed ?

Done

• Readonly anonymous classes - new readonly class {};
  • Tokenizer changes needed - PR PHP 8.3 | Tokenizer/PHP: add support for readonly anonymous classes #309
  • Updates needed to utility functions - getClassProperties()
  • Sniff updates needed - PRs PHP 8.3 | Add tests with readonly anonymous classes to various sniffs #323 + PHP 8.3 | PSR12/ClassInstantiation: allow for readonly anonymous classes #324
• Typed class constants

Is there any news on this? Dependencies seem to be released.

[jrfnl]

@leitommi What dependencies are you talking about ?

[leitommi]

I mean these PR-s are merged that were marked as "Blocked until":
#49
#78

I am mostly interested in typed class constants that were introduced in php 8.3.

Currently following code:

class A
{
  const int $MY_VAL;
}

produces following error, with phpcs 3.8.0:

phpcs: Generic.NamingConventions.UpperCaseConstantName.ClassConstantNotUpperCase: Class constants must be uppercase; expected INT but found int

[jrfnl]

For whoever cares - PR #309 is open adding tokenizer support for readonly anonymous classes and PR #321 adding tokenizer support for typed class constants.

Once those two are merged, support can be added to individual sniffs (and yes, the commits for this are ready and waiting).

The following three PRs have been opened to add support for PHP 8.3 typed class constants to various sniffs:

• PHP 8.3 | Generic/LowerCaseConstant: add support for typed constants #330
• PHP 8.3 | Generic/LowerCaseType: add support for typed constants #331
• PHP 8.3 | Generic/UpperCaseConstantName: add support for typed constants #332

Testing of these PRs would be appreciated.

Everything works as expected for me.✌️👍 When can we expect a release?

I can also confirm that everything is working correctly. 👍

@FabianKoestring @KeldorDE Thank you both for testing. Unless something unexpected happens, I'm hoping to release the 3.9.0 version towards the end of next week.

[jrfnl]

Version 3.9.0 has been tagged & released.

I'm leaving this issue open for now as the last bullet still needs to be investigated, though I don't really expect any issues with that syntax, but I'd rather be sure.
