mysql - php如何显示session的内容

Jun 06, 2016 pm 08:10 PM
mysql php session database

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

<code>if(isset($_SESSION["userId"])){
    echo $_SESSION["nickName"];
} </code>
Copy after login
Copy after login

如何能添加HTML代码,让他用类似

$_SESSION["nickName"]
的格式来显示

$_SESSION["nickName"]
的格式来显示

答案是{}大括号

<code><?php echo {$SESSION["nickname"]}
?>
</code>
Copy after login

我不懂,这个问题解决不了,我找到了,所以我Share出来,我说话不好听因为有人明明错了还出言不逊,难道你牛逼你就能瞧不起初学者,更何况,好像您水平一般吧?叫一群人来给负面评价什么的我都无所谓,你爱怎样怎也不会影响我,我是来学习不是来吵架的,己所不欲勿施于人不懂?

先学好基础再写代码。

<code>if(isset($_SESSION["userId"])) {
    echo $_SESSION["nickName"];
}</code>
Copy after login
Copy after login

直接这样:

<code>if(isset($_SESSION["userId"])){     
    echo {$_SESSION["nickName"]; 
} </code>
Copy after login

为啥还要加单引号啊?

<code>if(isset($_SESSION["userId"])) {
    echo $_SESSION["nickName"];
}</code>
Copy after login
Copy after login

亲,你加了''就意味着输出的是字符串.你去掉''之后才是SESSION变量

现在的人提问越来越牛逼了
