PHPStan extension that detects and blocks any usage of thecodingmachine/safe

ReactPHP Extension for PHPStan

Install

To install via Composer, use the command below, it will automatically detect the latest version and bind it with ^.

composer require wyrihaximus/phpstan-no-safe

Why

Main reason for this package is to prevent usage of thecodingmachine/safe in your codebase. And in my personal specific situation: I'm removing all usage of thecodingmachine/safe from my packages. This is something I started back when the packages wasn't maintained for a while and the decision was made to remove it. This package is purely a way to ensure there is nothing lingering around. It's the counterpart of thecodingmachine/phpstan-safe-rule. Also would like to note that I don't think thecodingmachine/safe is a bad package.

Usage

The rules in this package are automatically loaded by PHPStan when phpstan/extension-installer is installed.

Alternatively including the extension file from the root of this package will do the same:

includes:
	- vendor/wyrihaximus/phpstan-no-safe/extension.neon
