How does mysql-php display session content?

In the session, $ _ SESSION [& #039; nickName & #039;] is saved. In the subsequent menu bar, I want to display the user's nickName {code ...} how can I add HTML code to make it look like & amp; lt; div & amp; gt; $ _ SESSION [& quot; nickName & quot;] & amp; lt; the format of div & amp; gt; is saved in the session. $_SESSION['nickName']
In the subsequent menu bar, I want to display the nickname of the user

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

How can I add HTML code to make it look similar

$ _ SESSION ["nickName"]

To display

The answer is braces {}.

I don't understand. I can't solve this problem. I found it, so I Share it. I'm not good at speaking because someone makes a mistake and says nothing. Can you look down on beginners, what's more, it seems that you are normal? It doesn't matter if you call a group of people to give negative comments or anything. What do you like will not affect me. I come to learn, not to quarrel. Do you want to give it to others?

Learn the basics and then write code.

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

Directly:

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

Why should I add single quotes?

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

If you add '', it means that the output is a string. After you remove'', It is the SESSION variable.

Nowadays, people are getting better and better at asking questions.
