/**添加词库**/

//$data = ['我是日本人', 'sb','SB'];

$resTrie = trie_filter_new();

        foreach ($sensitiveWord['data'] as $k => $v) {

            trie_filter_store($resTrie, $v);

        }

        trie_filter_save($resTrie, $path . '/extensions/sensitive_word.tree');

        trie_filter_free($resTrie);

/**敏感词替换**/

$trieWord = trie_filter_load($path . '/extensions/sensitive_word.tree');

//$trieResult 返回找到的所有敏感词

//$arrRet 返回找到的1条敏感词

//

//$trieResult = trie_filter_search_all($trieWord, $content);

$arrRet = trie_filter_search($resTrie, $strContent);

$sensitiveWord = substr($content, $arrRet[0], $arrRet[1]);//通过substr获取匹配到的文字
