php-DFA-filterWord
==================

[](#php-dfa-filterword)

php实现基于确定有穷自动机算法的铭感词过滤

安装&使用流程
-----------

[](#安装使用流程)

### Download and install Composer:

[](#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

[](#安装扩展)

```
composer require jiangwu10057/dfa-sensitive

```

- 注意:如果你在使用composer安装时，出现
    Could not find package jiangwu10057/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

[](#如果你需要手动引入)

```
require './vendor/autoload.php';

use DfaFilter\SensitiveHelper;

```

### 构建敏感词库树

[](#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);

```

### 设置干扰因子集合

[](#设置干扰因子集合)

> 注意只干扰因子只支持单个字符或单个汉字，暂不支持词

> 但是多个干扰因子连在一起，敏感词可以准确识别

```
$handle = SensitiveHelper::init()->setStopWordList(['&', '*', '.'])->setTreeByFile($wordFilePath);

```

### 忽略大小写

[](#忽略大小写)

> 注意该设置只有在构建敏感词库树之前调用

> 在构建敏感词库树之后调用，结果可能不符合预期

```
$handle = SensitiveHelper::init()->setIgnoreCase()->setTree(['Av', '赌球网'])

```

### 检测是否含有敏感词

[](#检测是否含有敏感词)

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

```

### 敏感词过滤

[](#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

[](#标记敏感词)

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

```

### 获取文字中的敏感词

[](#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);

```

#### 使用composer自动加载php命名空间

[](#使用composer自动加载php命名空间)

```
$ composer update
```

### 运行单元测试

[](#运行单元测试)

```
$ composer test
```

注：本仓库fork自：[https://github.com/FireLustre/php-dfa-sensitive，](https://github.com/FireLustre/php-dfa-sensitive%EF%BC%8C) 现仅做个人学习使用！**建议使用原仓库！**

本fork在原有基础上

- 新增两个特性
    - getBadWord返回的敏感词列表是排查的，避免替换敏感词的出现重复替换的问题（提过PR，没有通过所以留个记录！）
    - 新增停止词功能，提高敏感词命中率
    - 新增忽略大小写功能
- ci的集成
