敏感词过滤,采用DFA算法

#敏感词过滤类 采用DFA算法

装载后数据结构如下：

  $words = [
      '小' => [
          '日' => [
              '本' => false,
          ],
      ],
      '日' => [
         '本' => [
             '鬼' => [
                  '子' => false,
              ],
              '人' => false,
          ],
      ],
  ];

使用：

    $disturbList = ['&', '*'];
    $data = ['日本册', '日本人', '大中华'];
    
    $wordObj = new TrieTree($disturbList);
    $wordObj->addWords($data);
    
    $txt = "日本加.不是.大中&华。。。";
    
    $words = $wordObj->search($txt);
    print_r($words);
    
    $txt = $wordObj->filter($txt);
    echo $txt, "\n";

输出：

Array
(
    [0] => 大中&华
)
日本加.不是.****。。。
