Error Identifier: method.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.
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');
