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。
