    $smarty=new Smarty();
    $smarty->template_dir="../php/tmps";
    $smarty->compile_dir="../php/tmps_c";
    $smarty->left_delimiter="<{";
    $smarty->right_delimiter="}>";

    $dsn = 'mysql:dbname=test;host=127.0.0.1';
    try{
    $dbh= new PDO($dsn, 'root', '123456');
    }catch(PDOException $e){
    echo "数据库连接失败:".$e->getMessage();
    }
    $dbh->exec("set names gbk");
    $rs=$dbh->query("SELECT * FROM student");
    $students=array();
    while($row=$rs->fetch(PDO::FETCH_ASSOC)){
            array_push($students,$row);
    }

    $db = null;
    $smarty->assign("students",$students);
    $smarty->display("mysql.tpl");
    ?>
     
    结果:
     
     
    注:数据库
