==================

[](#php-dfa-filterword)

### 安装扩展

[](#安装扩展)

```
    composer require guanhui07/dfa-sensitive

```

#### 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);
```
