PHP - 使会话在 X 分钟后过期

发布于 2024-09-25 02:55:19 字数 1110 浏览 8 评论 0原文

我正在使用以下技术...

从 login.php 表单发布到页面 check.php ，我在其中执行此操作

<?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");
}
?>

，并在 loggedin.php< /code> 页面我做的第一件事是，

<?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
}
?>

但是一旦登录，当我直接输入 url localhost\myProject\loggedin.php 时，它会显示该页面...这非常有意义，因为会话已经开始

我想要实现的是

直接 URL \ 会话在会话终止\过期\超时后工作 10 分钟，然后使用必须再次登录并可能获得相同的会话 ID，但 10 分钟后使用将无法使用同一会话进行浏览

我需要做什么或学习

i am using the following technique...

From the login.php the form posts to the page check.php where i do this

<?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");
}
?>

and on loggedin.php page the first thing i do is

<?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
}
?>

but once logged in when i directly type the url localhost\myProject\loggedin.php it displays the page...which makes perfect sense because the session has started

what i want to implement is

The direct URL \ session works for 10 minutes after that the session is terminated\expired\timed out and then use must login again and may get the same session id but after 10 minutes use won't be able to browse with the same session

WHAT DO I NEED TO DO OR LEARN

在会话中存储时间戳：

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

require ('DB_connection.php');

// Hey, always escape input if necessary!
$result = mysql_query(sprintf("SELECT * FROM accounts WHERE user_Name='%s' AND user_Pass='%s'", mysql_real_escape_string($uzer), mysql_real_escape_string($pass));

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

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

检查时间戳是否在允许的时间窗口内（600秒是10分钟）：

<?php
session_start();
if( !isset( $_SESSION['user_id'] ) || time() - $_SESSION['login_time'] > 600)
{
    header("Location:login.php");
}
else
{
    // uncomment the next line to refresh the session, so it will expire after ten minutes of inactivity, and not 10 minutes after login
    //$_SESSION['login_time'] = time();
    echo ( "this session is ". $_SESSION['user_id'] );
    //show rest of the page and all
}
?>

Store a timestamp in the session:

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

require ('DB_connection.php');

// Hey, always escape input if necessary!
$result = mysql_query(sprintf("SELECT * FROM accounts WHERE user_Name='%s' AND user_Pass='%s'", mysql_real_escape_string($uzer), mysql_real_escape_string($pass));

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

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

Check if the timestamp is within the allowed time window (600 seconds is 10 minutes):

<?php
session_start();
if( !isset( $_SESSION['user_id'] ) || time() - $_SESSION['login_time'] > 600)
{
    header("Location:login.php");
}
else
{
    // uncomment the next line to refresh the session, so it will expire after ten minutes of inactivity, and not 10 minutes after login
    //$_SESSION['login_time'] = time();
    echo ( "this session is ". $_SESSION['user_id'] );
    //show rest of the page and all
}
?>
