php - 当我注销时页面未正确重定向

Question

<?php
// Establishing Connection with Server by passing server_name, user_id and password as a parameter
include 'connection.php';

// session_start();

$user_check=$_SESSION['login_user'];
// SQL Query To Fetch Complete Information Of User

$ses_sql=mysqli_query($conn, "SELECT * FROM auth where email='$user_check'");
$row = mysqli_fetch_assoc($ses_sql);

$login_session =$row['email'];
$username =$row['name'];
$created_at =$row['created_at'];
$city =$row['city'];
$phone =$row['phone'];
$profile_photo =$row['photo'];

if(!isset($login_session)){
    mysqli_close($conn); // Closing Connection
    header('Location: index.php'); // Redirecting To Home Page
}
?>

我注释掉 session_start() 因为我已经在包含的另一个 php 文件中启动 session 。

我不明白为什么页面没有正确重定向到 index.php 文件。

Answer 1

取消注释您的 session 开始

session_start();

还要确保在开始 session 之前没有 html
