php-DFA-filterWord

php实现基于确定有穷自动机算法的铭感词过滤 https://packagist.org/packages/lustre/php-dfa-sensitive

安装&使用流程

Download and install Composer:

curl -sS https://getcomposer.org/installer | php

要检查 Composer 是否正常工作，只需要通过 php 来执行 PHAR

php composer.phar

安装扩展

composer require lustre/php-dfa-sensitive

注意:如果你在使用composer安装时，出现
Could not find package lustre/php-dfa-sensitive at any version for your minimum-stability (stable). Check the package spelling or your minimum-stability 请在你的composer.json中加入"minimum-stability": "dev"

如果你需要手动引入

require './vendor/autoload.php';

use DfaFilter\SensitiveHelper;

构建敏感词库树

场景一: 可以拿到不同（用户）词库数组

// 获取感词库索引数组
$wordData = array(
    '察象蚂',
    '拆迁灭',
    '车牌隐',
    '成人电',
    '成人卡通',
    ......
);

// get one helper
$handle = SensitiveHelper::init()->setTree($wordData);

场景二: 全站使用一套敏感词库

// 获取感词库文件路径
$wordFilePath = 'tests/data/words.txt';

// get one helper
$handle = SensitiveHelper::init()->setTreeByFile($wordFilePath);

检测是否含有敏感词

$islegal = $handle->islegal($content);

敏感词过滤

// 敏感词替换为*为例（会替换为相同字符长度的*）
$filterContent = $handle->replace($content, '*', true);

 // 或敏感词替换为***为例
 $filterContent = $handle->replace($content, '***');

标记敏感词

 $markedContent = $handle->mark($content, '<mark>', '</mark>');

获取文字中的敏感词

// 获取内容中所有的敏感词
$sensitiveWordGroup = $handle->getBadWord($content);
// 仅且获取一个敏感词
$sensitiveWordGroup = $handle->getBadWord($content, 1);

如何使用单元测试进行测试

安装PHPUnit

$ wget https://phar.phpunit.de/phpunit.phar

$ chmod +x phpunit.phar

$ mv phpunit.phar /usr/local/bin/phpunit

使用composer自动加载php命名空间

$ composer update

运行单元测试

$ phpunit tests/BaseTest.php
