Description
Category
stdlib · php-src-strict
Problem
Class constants whose value is an enum case (public const Color SWATCH = Color::Red) must report isEnumCase() === true. VM returns false.
| Repro | Zend 8.1+ | VM (2026-07-08) |
|---|---|---|
isEnumCase() on const Color SWATCH = Color::Red |
true |
false |
isEnumCase() on const int PLAIN = 1 |
false |
false |
