我需要让会话保持30分钟,然后将其销毁.

我正在使用以下技术......

从login.php表单帖子到check.php我执行此操作的页面

<?php    
$uzer = $_POST['user_name'];
$pass = $_POST['user_pass'];

require ('DB_connection.php');

$result = mysql_query("SELECT * FROM accounts WHERE user_Name='$uzer' AND user_Pass='$pass'");

if( mysql_num_rows( $result ) > 0)
{
    $array = mysql_fetch_assoc($result);    

    session_start();
    $_SESSION['user_id'] = $uzer;
    header("Location:loggedin.php");            
}
else
{
    header("Location:login.php");
}
?>

在loggedin.php页面上我做的第一件事就是

<?php
session_start();
if( !isset( $_SESSION['user_id'] ) )
{
    header("Location:login.php");
}
else
{
    echo ( "this session is ". $_SESSION['user_id'] );
    //show rest of the page and all
}
?>

但是当我直接输入网址时登录后localhost\myProject\loggedin.php …
