[junichi11]

PHP 8.1 Support: New in initializers (Part 5)

• https://issues.apache.org/jira/browse/NETBEANS-5599
• RFC:https://wiki.php.net/rfc/new_in_initializers
• Support for field and method access for constant (e.g. const C = new A(); C->field; C->method();)
• Fix the parser
• Fix PHP81UnhandledError

PHP 8.2 Support: Fetch properties of enums in const expressions (Part 1)

• PHP 8.2 Support #4725
• https://wiki.php.net/rfc/fetch_property_in_const_expressions
• Fix the grammar file
• Fix CC: add the readonly name property to enums
• Add/Fix unit tests for the parser and CC

Note

The following code is valid but I don't think these are meaningful. So, I don't support these cases at the moment.

const A = (null)?->test;

const B = (null)?->test->test;

const C = (null)->test?->test;

const D = (null)?->test['test'];

const E = (null)['test']?->test;

const F = (null)?->{new Printer};

const G = (null)?->test + (new Printer ? 1 : 0);

const H = (1)->prop;

const I = (1)?->prop;
