1、扩展安装

composer require lustre/php-dfa-sensitive

 2、推荐的敏感词库

https://codeload.github.com/jkiss/sensitive-words/zip/refs/heads/master

3、使用：

  把下载好的词库放到项目本地

  直接上代码：

use DfaFilter\SensitiveHelper;

public static function checkSensitiveWords($words)
    {
        $route = __DIR__.  '/../extends/Sensitive_words.txt';
        $word = file_get_contents($route);
        $sensitiveWords = explode(",",$word);
        $handle = SensitiveHelper::init()->setTree($sensitiveWords);//构建敏感词库树
        $isLegal = $handle->islegal($words);//是否有敏感词
        if($isLegal) {
            $words = $handle->replace($words, '***');//敏感词替换成***
        }
        return $words;
    }
