php如何显示session的内容?

Question

在session中保存了$_SESSION['nickName']
在后来的菜单栏中，我想要显示用户的这个昵称

if(isset($_SESSION["userId"])){    echo $_SESSION["nickName"];
}

如何能添加HTML代码，让他用类似<div> $_SESSION["nickName"] </div> 的格式来显示

Answer 1

先学好基础再写代码。if(isset($_SESSION["userId"]))&nbsp;{&nbsp;&nbsp;&nbsp;&nbsp;echo&nbsp;$_SESSION["nickName"]; }

Answer 2

直接这样：if(isset($_SESSION["userId"])){&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;echo&nbsp;{$_SESSION["nickName"];&nbsp; }为啥还要加单引号啊？

Answer 3

if(isset($_SESSION["userId"]))&nbsp;{&nbsp;&nbsp;&nbsp;&nbsp;echo&nbsp;$_SESSION["nickName"]; }
