To use this extension, require it in Composer:

composer require --dev phpstan/phpstan-deprecation-rules

Manual installation

If you don't want to use phpstan/extension-installer, include rules.neon in your project's PHPStan config:

    - vendor/phpstan/phpstan-deprecation-rules/rules.neon

Deprecating code you don't own

This extension emits deprecation warnings on code, which uses properties/functions/methods/classes which are annotated as @deprecated.

In case you don't own the code which you want to be considered deprecated, use PHPStan Stub Files to declare deprecations for vendor files like:

/** @deprecated */
class ThirdPartyClass {}
