# InvalidInterfaceImplementation
|
|
|
|
Emitted when trying to implement interface that cannot be implemented (e.g. `Throwable`, `UnitEnum`, `BackedEnum`).
|
|
|
|
```php
|
|
<?php
|
|
|
|
class E implements UnitEnum
|
|
{
|
|
public static function cases(): array
|
|
{
|
|
return [];
|
|
}
|
|
}
|
|
```
