最近项目有需求，要对用户的签名，回复进行敏感词检测，然后搜到了一个好用的扩展，分享给大家。
https://github.com/FireLustre/PHP-dfa-sensitive
通过 composer 进行安装：
composer require lustre/PHP-dfa-sensitive
然后在 app 目录下创建 Services ，并添加 SensitiveWords.PHP
<?PHP
namespace App\Services;
use DfaFilter\SensitiveHelper;
class SensitiveWords
{
protected static $handle = null;
private function __construct()
{
}
private function __clone()
{
}
/**
* 获取实例
*/
public static function getInstance($word_path = [])
{
if (!self::$handle) {
//默认的一些敏感词库
$default_path = [
storage_path('dict/bk.txt'),storage_path('dict/fd.txt'),storage_path('dict/ms.txt'),storage_path('dict/qt.txt'),storage_path('dict/sq.txt'),storage_path('dict/tf.txt'),];
$paths = array_merge($default_path,$word_path);
self::$handle = SensitiveHelper::init();
if (!empty($paths)) {
foreach ($paths as $path) {
self::$handle->setTreeByFile($path);
}
}
}
return self::$handle;
}
/**
* 检测是否含有敏感词
*/
public static function isLegal($content)
{
return self::getInstance()->islegal($content);
}
/**
* 敏感词过滤
*/
public static function replace($content,$replace_char = '',$repeat = false,$match_type = 1)
{
return self::getInstance()->replace($content,$replace_char,$repeat,$match_type);
}
/**
* 标记敏感词
*/
public static function mark($content,$start_tag,$end_tag,$match_type = 1)
{
return self::getInstance()->mark($content,$match_type);
}
/**
* 获取文本中的敏感词
*/
public static function getBadWord($content,$match_type = 1,$word_num = 0)
{
return self::getInstance()->getBadWord($content,$match_type,$word_num);
}
}
然后我们就可以在项目中，使用 SensitiveWords::getBadWord() 来获取文本中是否有敏感词。
$bad_word = SensitiveWords::getBadWord($content);
if (!empty($bad_word)) {
throw new \Exception('包含敏感词:' . current($bad_word));
}
在 storage 目录下创建 dict 目录存放敏感词词库，bk.txt .....等等，这些词库都是我在网上下载的。
