The index controller writes the following two methods:

Class Index extends controller{public    function Index ()    {            $params = array (' title ' = = ' This is the new record title ', ' Content ' = ' This is a new record ', ' Addtime ' =>date (' y-m-d h:i:s '));        $result = Db::execute (' INSERT into lsf_article (Title,content,addtime) VALUES (: Title,:content,:addtime) ', $params);        Sleep (a);        $lastid =db::getlastinsid ();        echo $lastid;    }    Public Function test () {        $params = array (' title ' = ' = ' This is a new record title2 ', ' content ' = ' This is a new record 2 ', ' addtime ' = Date (' y-m-d h:i:s '));        $result = Db::execute (' INSERT into lsf_article (Title,content,addtime) VALUES (: Title,:content,:addtime) ', $params);        $lastid =db::getlastinsid ();        echo $lastid;    }}
