How to close a Session in PHP

I’m having trouble trying to destroy the sessions, I tried the code below, there is some way beyond that?

<?php
    session_start();
    session_destroy();
    header('Location: index.php');
?>

What happens is that the session variables are not destroyed, thus being able to rescue the values contained in it.

php

  • What do you mean by "end sessions"?

  • I am trying to make the user perform the "logoff"

  • Have you read the job documentation session_destroy()?

  • Unfortunately, I don’t know what went wrong. When I do Logoff it performs redirection to the page "Index.php" but when I force access to another page like "Home.php", It enters the page usually as if I were logged in. <? php session_start(); session_destroy(); header('Location: index.php'); ? > This is my code for "logoff"

  • The question became clearer?

  • No, what was the "problem" you’re having?

  • The question has already been answered, I’m trying to make it clearer with the standards of the site. I’ll edit it again.

To log out you should use this in your PHP code.

session_destroy();

If you want to create a session you can do so in your PHP code:

session_start();

$_SESSION['usuario'] = "User1";

If you want to get some session value in your PHP code:

echo $_SESSION['usuario'];

  • When I do Logoff it performs redirection to the page "Index.php" but when I force access to another page like "Home.php", It enters the page usually as if I were logged in. <? php session_start(); session_destroy(); header('Location: index.php'); ? > This is my code for "logoff"

  • Try to make some changes: I will paste as a response.

Make the following change at Home.php in the first line of code:

<?php
    session_start();
    /* Aqui você está verificando se a sessão está setada,
     * quando ele fizer logoff, seu session_destroy fará com que ele não entre na página
     */
    if(!isset($_SESSION['logged_in'])){
        header('Location: index.php');
    }
?>

Then modify the login as well. Add this code if the login was successfully done:

...
$_SESSION['logged_in'] = true;
...

Try to make some changes:

On your "App Help Desk" page remove the excerpt:

session_destroy();

header('Location: index.php');

Create a page with the name: logoff.php

and paste the code below in logoff.php

session_destroy();

header('Location: index.php');
