Bug #81517 [Opn]: Bug in enums implementation.

Edit report at https://bugs.php.net/bug.php?id=81517&edit=1 ID: 81517 Updated by: nikic@php.net Reported by: general at langivi dot technology Summary: Bug in enums implementation. Status: Open Type: Bug Package: *General Issues Operating System: linux PHP Version: 8.1.0RC3 Block user comment: N Private report: N New Comment: Please use the following APIs to work with enums in extensions: ZEND_API zend_class_entry *zend_register_internal_enum( const char *name, zend_uchar type, const zend_function_entry *functions); ZEND_API void zend_enum_add_case(zend_class_entry *ce, zend_string *case_name, zval *value); ZEND_API void zend_enum_add_case_cstr(zend_class_entry *ce, const char *name, zval *value); ZEND_API zend_object *zend_enum_get_case(zend_class_entry *ce, zend_string *name); ZEND_API zend_object *zend_enum_get_case_cstr(zend_class_entry *ce, const char *name); Additionally, you can declare enums in stubs. The zend_enum_get_case() functions are used to create enum objects. However, it is not possible to easily use an enum value as a property default value right now, because it would require a CONSTANT_AST default value that performs a class constant lookup.
