在iPhone网络应用程序上维护PHP会话 [英] Maintaining a PHP session on an iPhone web app

问题描述

我刚刚在我的iPhone上创建了一个网络应用程序。我可以打开它，没有问题，登录，但每当我返回到应用程序，它忘记了我的上一个会话，我必须重新输入我的用户名和密码。

I've just created a web app on my iPhone. I can open it and log in with no problem, but whenever I return to the app it has forgotten my previous session and I have to re-enter my username and password.

有关于此的一些其他问题，但他们的答案没有帮助我解决这个问题，因为我不知道放在哪里提供的PHP。

There have been a few other questions about this, but their answers haven't helped me to solve the problem because I'm not sure where to put the PHP that was provided.

这是我找到的最佳答案：在iPhone上的网络应用中维护PHP会话

This is the best answer that I've found: Maintain PHP Session in web app on iPhone

在答案中，Wilbo Baggins（http://stackoverflow.com/users/346440/wilbo-baggins ）提供了以下代码：

In the answer, Wilbo Baggins (http://stackoverflow.com/users/346440/wilbo-baggins) provides the following code:

// Start or resume session
session_start(); 

// Extend cookie life time by an amount of your liking
$cookieLifetime = 365 * 24 * 60 * 60; // A year in seconds
setcookie(session_name(),session_id(),time()+$cookieLifetime);

我在<？php 和？> 标签，但是没有解决问题。我猜我把它放在错误的地方，所以我寻找指导，将解释我应该把它放在哪里。

I entered that code between <?php and ?> tags in the website's header, but that hasn't solved the issue. I'm guessing that I'm putting it in the wrong place, so I'm looking for guidance that will explain where I should actually be putting it.

谢谢。

推荐答案

在您的login.php中，添加以下代码登录信息正确：

In your login.php, add the following code when login information correct:

session_start();

//your code here

if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']),"apple")) //to prevent cookies for non-apple devices
{
    $cookieLifetime = 365 * 24 * 60 * 60; // A year in seconds
    setcookie("ses_id",session_id(),time()+$cookieLifetime);
}

然后，在每个其他* .php中，您希望恢复session_id，在session_start（）之前添加以下行：

Then, in every other *.php you want your session_id to be restored, add the following line BEFORE session_start():

if($_COOKIE['ses_id']){
    session_id($_COOKIE['ses_id']);
}
session_start();

在您的logout.php中，添加以下代码：

In your logout.php, add the following code:

session_start();
$cookieLifetime = 365 * 24 * 60 * 60; // A year in seconds
setcookie("ses_id","",time()-$cookieLifetime); //set lifetime to negative to autodelete cookie
session_destroy();

希望这有帮助。
