我想让这个blog.php页面把登陆的用户名打印出来应该怎么写呢？

blog.php

cookie页面

login.php

prepare("select id,username,password from user where username=? and password=?");
 $stmt->execute(array($_POST['username'],($_POST['password'])));
 if($stmt->rowCount()>0){
 list($id,$username)=$stmt->fetch(PDO::FETCH_NUM);
   $time=time()+24*60*60;
   setCookie("uid",$id,$time,"/");
   setCookie("username",$username,$time,"/");
   setCookie("isLogin",1,$time,"/");
   echo '';
 }
 else{
     echo "登陆失败";
 }
 }
?>

回复内容：

blog.php

cookie页面

login.php

prepare("select id,username,password from user where username=? and password=?");
 $stmt->execute(array($_POST['username'],($_POST['password'])));
 if($stmt->rowCount()>0){
 list($id,$username)=$stmt->fetch(PDO::FETCH_NUM);
   $time=time()+24*60*60;
   setCookie("uid",$id,$time,"/");
   setCookie("username",$username,$time,"/");
   setCookie("isLogin",1,$time,"/");
   echo '';
 }
 else{
     echo "登陆失败";
 }
 }
?>

setCookie("username",$username,$time,"/");

echo $username;//打印用户名
