Error Identifier: catch.deprecatedClass

Every error reported by PHPStan has an error identifier. Here’s a list of all error identifiers. In PHPStan Pro you can see the error identifier next to each error and filter errors by their identifiers.

Code example #

<?php declare(strict_types = 1);

/** @deprecated Use NewException instead */
class OldException extends \Exception
{
}

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

Why is it reported? #

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

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

How to fix it #

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

 <?php declare(strict_types = 1);
 
 try {
     // ...
-} catch (OldException $e) {
+} catch (NewException $e) {
     // ...
 }

How to ignore this error #

You can use the identifier catch.deprecatedClass to ignore this error using a comment:

// @phpstan-ignore catch.deprecatedClass
codeThatProducesTheError();

You can also use only the identifier key to ignore all errors of the same type in your configuration file in the ignoreErrors parameter:

parameters:
	ignoreErrors:
		-
			identifier: catch.deprecatedClass
