注意:未定义的索引:会话PHP

This error only shows if user is not logged-in. I understand there are already a couple of errors like this, ive tried my best to test them all. but i still cant figure this out.

Notice: Undefined index: user_session in ..index.php on line 10

<?php 
session_start();

if (session_status() == PHP_SESSION_NONE){
    header('Location: index.php');
}

if (session_status() == PHP_SESSION_ACTIVE) {
   $session = $_SESSION['user_session']; //line 10
}

此错误仅显示用户是否未登录。 我知道已经有这样的一些错误,我已尽力测试它们。 但我仍然无法弄清楚这一点。

注意:未定义的索引:第10行的..index.php中的user_session

 &lt;?  php 
session_start(); 
 
if(session_status()== PHP_SESSION_NONE){
 header('Location:index.php'); 
} 
 
if(session_status()== PHP_SESSION_ACTIVE){
  $ session = $ _SESSION ['user_session'];  //第10行
}

    When user logs in , you have to set this $_SESSION["user_session"]=$value; first then only you will be able to access it. You are trying to access a variable which you haven't set anywhere. So its throwing undefined index.
