Linking logout button in html to logout php

Question

Does anyone know why my logout button isn't working? I have created a button in my HTML which looks like this:

<button  href="logout.php">Logout </button>

And then I have a PHP file called logout.php which looks like this:

 <?php
session_start();

if(session_destroy()) {
  header("Location: index.html");
}
?>

I don't know how to connect the two. If anyone could help me that would be great.

What happens? One should end up in the index.html – halojoy Dec 23 '17 at 14:30 — halojoy, Dec 23 '17 at 14:30

You can call the PHP file using the bellow code.

As far as I know you can call an href directly from a button. Either you should use an anchor tag or a form to submit to particular a link. Here is the thread related to your query

<a href="your link..." class="btn btn-success">Logout</a>

It can not work on old php version. What is your PHP version? Or you may try session_unset() instead of session_destroy().

There is anchor tag to redirect a page . But you want to use button then it can achieve by using javascript

  <button onclick="window.location.href='logout.php'">Logout</button>

Change

 <button  href="logout.php">Logout </button>

To

 <button><a href="logout.php">Logout</a></button>
