Only this is necessary
只有这个是必要的
session_start();
unset($_SESSION["nome"]); // where $_SESSION["nome"] is your own variable. if you do not have one use only this as follow **session_unset();**
header("Location: home.php");

<?php //initialize the session if (!isset($_SESSION)) { session_start(); }
// ** Logout the current user. **
$logoutAction = $_SERVER['PHP_SELF']."?doLogout=true";
if ((isset($_SERVER['QUERY_STRING'])) && ($_SERVER['QUERY_STRING'] != "")){
$logoutAction .= "&". htmlentities($_SERVER['QUERY_STRING']);
}
if ((isset($_GET['doLogout'])) &&($_GET['doLogout']=="true")) {
// to fully log out a visitor we need to clear the session variables
$_SESSION['MM_Username'] = NULL;
$_SESSION['MM_UserGroup'] = NULL;
$_SESSION['PrevUrl'] = NULL;
unset($_SESSION['MM_Username']);
unset($_SESSION['MM_UserGroup']);
unset($_SESSION['PrevUrl']);
$logoutGoTo = "index.php";
if ($logoutGoTo) {
header("Location: $logoutGoTo");
exit;
}
} ?>
