catch.deprecatedEnum

Code example

<?php declare(strict_types = 1);

/** @deprecated Use NewException instead. */
enum AppError: string implements \Throwable
{
    // ...
}

try {
    // ...
} catch (AppError $e) {
    // ...
}

Why is it reported?

The catch clause references an enum that has been marked with a @deprecated PHPDoc tag. The enum is scheduled for removal or replacement, and any usage of it -- including catching it -- should be migrated to the recommended alternative.

This rule is provided by the phpstan-deprecation-rules package.

How to fix it

Replace the deprecated enum with its recommended replacement as indicated in the deprecation message:

 <?php declare(strict_types = 1);

 try {
     // ...
-} catch (AppError $e) {
+} catch (NewException $e) {
     // ...
 }
