enum.duplicate - Phpstan

Code example

This error is reported when the same enum name is declared in multiple files within the analysed codebase:

php

// file1.php
<?php declare(strict_types = 1);

namespace App;

enum Status
{
    case Active;
    case Inactive;
}

php

// file2.php
<?php declare(strict_types = 1);

namespace App;

enum Status
{
    case Pending;
    case Completed;
}

The same enum name is declared multiple times within the registered stub files.

Remove the duplicate enum declaration, keeping only one:

diff-php

 <?php declare(strict_types = 1);

 // file2.php
 namespace App;

-enum Status
-{
-    case Pending;
-    case Completed;
-}

If both declarations are intentionally different, rename one of them:

diff-php

 <?php declare(strict_types = 1);

 // file2.php
 namespace App;

-enum Status
+enum TaskStatus
 {
     case Pending;
     case Completed;
 }
