使用
生成敏感词库
$arrWord = array('word1', 'word2', 'word3'); $resTrie = trie_filter_new(); //create an empty trie tree foreach ($arrWord as $k => $v) { trie_filter_store($resTrie, $v); } trie_filter_save($resTrie, __DIR__ . '/blackword.tree'); trie_filter_free($resTrie);
使用
$resTrie = trie_filter_load(__DIR__ . '/blackword.tree'); $strContent = 'hello word2 word1'; $arrRet = trie_filter_search($resTrie, $strContent); print_r($arrRet); //Array(0 => 6, 1 => 5) echo substr($strContent, $arrRet[0], $arrRet[1]); //word2 $arrRet = trie_filter_search_all($resTrie, $strContent); print_r($arrRet); //Array(0 => Array(0 => 6, 1 => 5), 1 => Array(0 => 12, 1 => 5)) foreach ($arrRet as $item) { echo substr($strContent, $item[0], $item[1]); //word2 word1 } $arrRet = trie_filter_search($resTrie, 'hello word'); print_r($arrRet); //Array() trie_filter_free($resTrie);
以上就是php敏感词过滤使用第三方扩展trie_filter的内容,更多相关内容请关注PHP中文网(www.php.cn)!
