# DuplicateEnumCaseValue
Emitted when a backed enum has duplicate case values.
```php
<?php
enum Status: string
{
case Open = "open";
case Closed = "open";
}
```
## How to fix
Change case values so that there are no duplicates.
```php
<?php
enum Status: string
{
case Open = "open";
case Closed = "closed";
}
```
