Can you try this, Because of, in your code you have setting expire time each & every time the page gets load, now added condition.
你能试试这个吗，因为，在你的代码中，你每次和每次页面加载时都设置了过期时间，现在添加了条件。
@session_start();
if(!isset($_SESSION['uname']) || $_SESSION['uname'] == " " || !isset($_SESSION['uid']) || $_SESSION['uid'] == " ")
{
echo "<script language='javascript'>";
echo "window.location='../index.php'";
echo "</script> ";
exit;
}
$_SESSION['start'] = time(); // taking now logged in time
if(!isset($_SESSION['expire'])){
$_SESSION['expire'] = $_SESSION['start'] + (1* 10) ; // ending a session in 30 seconds
}
$now = time(); // checking the time now when home page starts
if($now > $_SESSION['expire'])
{
session_destroy();
echo "Your session has expire ! <a href='logout.php'>Click Here to Login</a>";
}
else
{
echo "This should be expired in 1 min <a href='logout.php'>Click Here to Login</a>";
}
