method.deprecatedClass

This error is reported by phpstan/phpstan-deprecation-rules.

Code example

<?php declare(strict_types = 1);

/** @deprecated Use NewLogger instead */
class OldLogger
{
	public function log(string $message): void
	{
	}
}

$logger = new OldLogger();
$logger->log('hello');

Why is it reported?

A method is being called on an instance of a class that has been marked as @deprecated. Even though the method itself is not deprecated, the entire class is deprecated, which means all usage of the class -- including calling its methods -- should be replaced with the suggested alternative.

How to fix it

Replace the usage of the deprecated class with its recommended replacement.

 <?php declare(strict_types = 1);

-$logger = new OldLogger();
+$logger = new NewLogger();
 $logger->log('hello');
