phpcs:如何执行类继承？

Question

我想确保某些dir (src/Controller/CP)中的所有类都扩展了其他类AbstractCPController。

所以

class SupportTicketTagController extends AbstractController

将显示PHPCS错误，以及

class SupportTicketTagController extends AbstractCPController

会很好的。

有可能用PHPCS吗？

最后我创造了我自己的嗅觉。它远非十全十美，但可能成为未来某个人的基础：

<?php

declare(strict_types=1);

use PHP_CodeSniffer\Fixer;
use PHP_CodeSniffer\Sniffs\Sniff;
use PHP_CodeSniffer\Files\File;

    private ?Fixer $fixer;

    private $position;

        $className = $tokens[$file->findNext(T_STRING, $position + 1)]['content'];

        if ($className === 'AbstractCPController') {
            return;
        }

            $lastClassName = '';

            for ($i = $extendsLine + 1; $i < $extendsLineMax; $i++) {
                if ($tokens[$i]['code'] == T_STRING || $tokens[$i]['code'] == T_NS_SEPARATOR) {

        $file->addError(

            self::class
        );
    }
}
