在php中无效15分钟后自动注销

I want to destroy session if users are not doing any kind of activity on website. At that time after 5 users automatically redirect on index page. How is it possible? Is possible in php with session handling and for that I have to maintain or update user login time or not..

如果用户没有在网站上进行任何类型的活动,我想破坏会话。此时5个用户自动重定向索引页面。这怎么可能?可以在php中进行会话处理,为此我必须维护或更新用户登录时间。

Pretty easy:

 if(time() - $_SESSION['timestamp'] > 900) { //subtract new timestamp from the old one
    echo"<script>alert('15 Minutes over!');</script>";
    unset($_SESSION['username'], $_SESSION['password'], $_SESSION['timestamp']);
    $_SESSION['logged_in'] = false;
    header("Location: " . index.php); //redirect to index.php
    exit;
} else {
    $_SESSION['timestamp'] = time(); //set new timestamp
}

I got this solution from Sitepoint.com Using a simple meta tag in your html

我从Sitepoint.com获得了这个解决方案在你的html中使用了一个简单的元标记

<meta http-equiv="refresh" content="900;url=logout.php" />

The 900 is the time in seconds that you want the session to be terminated if inactive.

900是您希望会话在非活动状态下终止的时间(以秒为单位)。

Hope it works for you

My Solution Is (i give you solution but this simple and syntax not been tried)

我的解决方案是(我给你解决方案,但这个简单和语法没有尝试过)

checkerOrCreatorTime.php

<?php
//if using the session, this additional advice me
ini_set('session.cookie_httponly', 1);
ini_set('session.use_only_cookies', 1);
session_start();
//create session (JUST FOR ONE TIME)
if (!isset($_SESSION['THE SESSION KEY FOR LOGIN (EX. USERNAME)'])){
    //create anyting session you need
    $_SESSION['user']['THE SESSION KEY FOR LOGIN (EX. USERNAME)'] = 'USER';
    $_SESSION['user']['TIME'] = '900';
}else
if (time() -$_SESSION['TIME'] > 900){
    unset($_SESSION['user']);
    // and whatever your decision
}
?>

Faq:

 1. Why use ['user'] is session login?
    if you using many session for user, you just unset one var, like this.

 2. why use a ini_set.... in this syntax?
    for more security

if you like using modern web, just using javascript for ajax

如果你喜欢使用现代网络,只需使用javascript进行ajax

<form action="index.php" method="post" name="frm"><input name="uname" type="text" placeholder="User Name" />

<input name="submit" type="submit" value="submit" /></form>
In index.php
<?php if(isset($_SESSION['loggedAt'])) { header('dashboard.php'); }

session_Start(); $_SESSION['username']=$name; $_SESSION['loggedAt']=time(); header('location:dashboard.php?msg=Welcome to dashboard'); } } ?>
