Session_unset and session_destroy not working

Question

Was just wondering why my code isn't working here:

<?php
    session_start();
    if (isset($_SESSION)) {
      session_unset();
      session_destroy();
    }
?>

I've tried printing out the result of echo isset($_SESSION) and it returns true, and my pages that require login are still allowing me to access them.

You must definitely define a variable as session

for example:

LOGIN

<?php
session_start();
if($_POST['username']){
$_SESSION['username'] =$_POST['username']; // session run
}
?>

LOGOUT

<?php
    session_start();
    if($_POST['LOGOUT']=='exit'){
@session_unset();
    }
    ?>

You can also use unset($_SESSION['username']); instead of session_unset();
