programming php PHP logout script

Hướng dẫn which php function is used to make a user logged out from a website? - chức năng php nào được sử dụng để làm cho người dùng đăng xuất khỏi một trang web?

Tôi có thể thấy hai lỗi trong mã của bạn:

  • Bạn chưa bắt đầu phiên
  • Bạn chưa nói với mã phiên nào để hủy/phá hủy

Bắt đầu phiên:

Đặt đây làm dòng đầu tiên của mã PHP của bạn: session_start[];

Đăng xuất

Hãy xem xét kỹ hơn khối mã này:

if [isset[$_SESSION['loggedin']] && [time[] - $_SESSION['loggedin'] > 1800]] {
    // last request was more than 30 minutes ago
    session_unset[];     // unset $_SESSION variable for the run-time 
    session_destroy[];   // destroy session data in storage
}

Bạn chưa nói với mã phiên nào cho unset hoặc destroy!

Để làm điều đó, bạn phải bao gồm một biến phiên bên trong dấu ngoặc đơn.

Thử mã này:

if [isset[$_SESSION['loggedin']] && [time[] - $_SESSION['loggedin'] > 1800]] {
// last request was more than 30 minutes ago
session_unset[$_SESSION['loggedin']];     // unset $_SESSION variable for the run-time 
session_destroy[$_SESSION['loggedin']];   // destroy session data in storage
}

Tất cả những gì tôi đã làm là, đã nói với mã phiên nào cho unset và destroy

Cập nhật thử điều này thay vào đó nếu điều đó không hoàn toàn phù hợp với bạn.
Try this instead if that didn't quite work for you.

if [isset[$_SESSION['loggedin']] && [time[] - $_SESSION['loggedin'] > 1800]] {
// last request was more than 30 minutes ago
unset[$_SESSION['loggedin']];     // unset $_SESSION variable for the run-time 
$_SESSION['loggedin'] = "false";
}

Một điều tốt khác để xem xét là có một nút đăng xuất. Điều này được giải thích ở đây: Nút đăng nhập PHP

Tôi hy vọng điều này đã giúp bạn ra ngoài, và cho tôi biết nếu tôi có thể giúp đỡ thêm!

Trong các trang web mạng xã hội như Facebook, Instagram, v.v., tên người dùng và hình ảnh hồ sơ của người dùng đã đăng nhập được hiển thị trong tiêu đề của trang web và tiêu đề đó vẫn không đổi, không phân biệt trang web mà người dùng đã mở. Chức năng đó có thể được tạo bằng cách sử dụng các biến phiên. & NBSP; Các biến phiên chỉ tồn tại trong khi phiên của người dùng đang hoạt động. Sau khi phiên hoàn tất, các biến phiên bị phá hủy. Đây là duy nhất cho mỗi khách truy cập và thường được sử dụng để lưu trữ thông tin dành riêng cho người dùng như tên người dùng, ảnh hồ sơ, v.v., sau khi người dùng đăng nhập. & NBSP; Mã: & nbsp; Đây là một hệ thống đăng ký đơn giản. Trang đăng ký.php yêu cầu tên người dùng, email và mật khẩu mong muốn của người dùng, sau đó gửi dữ liệu đã nhập vào cơ sở dữ liệu, sau khi nhấp vào nút gửi. Sau đó, người dùng được chuyển hướng đến trang index.php trong đó tin nhắn chào mừng và tên người dùng của người dùng đã đăng nhập được hiển thị. Bước đầu tiên là tạo cơ sở dữ liệu và sau đó là một bảng bên trong nó. Cơ sở dữ liệu được đặt tên là ‘Đăng ký, và bảng được đặt tên là‘ người dùng. Bảng ‘người dùng sẽ chứa 4 trường. & NBSP;session variables. 
Session variables exist only while the user’s session is active. After the session is complete, the session variables get destroyed. These are unique for each visitor and are generally used to store user-specific information such as the username, profile picture etc, once the user logs in. 
The session variables are used to display logged in user information in PHP.
Project Explanation and Code: 
This is a simple registration system. The register.php page asks for the desired username, email, and password of the user, and then sends the entered data into the database, once the submit button is clicked. After this, the user is redirected to the index.php page where a welcome message and the username of the logged-in user is displayed.
The first step is to create a database, and then a table inside it. The database is named ‘registration’, and the table is named ‘users’. The ‘users’ table will contain 4 fields. 

  1. ID - Khóa chính - Tăng tự động
  2. Tên người dùng - Varchar [100]
  3. Email - Varchar [100]
  4. Mật khẩu - Varchar [100] ‘ID, sẽ là khóa chính, điều đó có nghĩa là nó sẽ là duy nhất cho mỗi người dùng đã đăng ký. Nó cũng sẽ tự động tăng cho mỗi đăng ký mới. Kiểu dữ liệu cho tên người dùng, email và mật khẩu sẽ là varchar. Kích thước có thể được điều chỉnh theo yêu cầu tuy nhiên, 100 là đủ.sql mã cho bảng: & nbsp; & nbsp;
    The ‘id’ will be the primary key, it means that it will be unique for every registered user. It will also auto-increment for every new registration. The data type for username, email and password will be varchar. The size can be adjusted as per the requirement however, 100 is sufficient.
    SQL code for the table:

05 The session is started using session_start[] method. After that, the variables are declared and an error array is created. It will store all the error messages. The server.php page is then connected to the ‘registration’ database created earlier. After the user clicks the ‘register’ button on the register.php button, the data entered is sent to the database, and this completes a new registration. However, form validation is done before that to make sure that the user is filling the form correctly. All the fields are required and cannot be left blank.
Line 18 – 21: mysqli_real_escape_string escapes the special characters before sending the data to the database. This is essential for database security from SQL injections.
Line 25 – 27: These lines makes sure that the user is filling all the input boxes, and whether the ‘password’ and ‘confirm password’ matches. If both the password matches, then the code further runs.
Line 29 – 32: Checking whether the password matches or not. 
Line 35 – 46: If the number of errors until this point is zero, the password is then ‘md5’ encrypted and the data entered is sent to the database. After the registration process is complete, the username is stored in the session variable, and the user is redirected to the index.php page, where he is asked to enter the login credentials.
Line 50 – 80: First the username and password entered in sanitized. This is essential to increase database security, as it eliminates the chances of any SQL injection. The user gets an error message if the username or the password field is left blank. 
If the number of errors until this point of code is found to be 0, then a database check is run. If the username entered by the user is found to be present in the database, then the user successfully logs in. The user is then redirected to the ‘index.php’ page.

Line 01 – 19: The username that was stored in the session variable is now displayed back to the user. This session variable can either be destroyed using unset[$_SESSION[“products”]] or session_destroy[]. However, session_destroy[] will destroy all the session variables at once. To destroy only the ‘username’ session variable, it will be better to unset the variable using unset[$_SESSION[“products”]].
