推荐答案

从大多数情况下，Web应用程序无法从中断处继续，因为用户正在存储Web应用程序图标（假设在iOS设备上）在其主屏幕上实际上是一个书签，它只是在返回到Web应用程序时将该特定网页作为Web应用程序启动。

It's not (for the most part) possible for a web app to resume where it left off, because since the user is storing the web app icon (assuming on an iOS device) as what is essentially a bookmark on their homescreen, it just launches that specific web page as the web app when they go back into the web app.

然而，你可以做的是设置一个cookie（通过PHP或Javascript）等于用户每次在移动应用中查看页面时正在查看的完整URL。例如（在PHP中）：

What you COULD do however, is set a cookie (via PHP or Javascript) equal to the full URL that the user is viewing every time the user views a page in the mobile app. For example (in PHP):

//--- Set lastPage cookie for 24 hrs for your domain --- //
setcookie('lastPage', 'http://www.example.com/products/bicycles', time()+86400, '/');

答案：

在您的主页上，在显示任何内容之前，如果设置了 $ _ COOKIE ['lastPage'] ，请使用PHP（或选择的语言）进行检查。如果是，请执行if语句将用户重定向到最后查看的页面。

On your homepage, before displaying any content, check with PHP (or language of choice) if $_COOKIE['lastPage'] is set. If it is, perform an if statement redirecting the user to that last viewed page.

<?php
    if(isset($_COOKIE['lastPage'])) {
        header('location: '.$_COOKIE['lastPage']);
        exit();
    } 
?>

这对用户来说是无缝的，并且会使其看起来好像网络应用程序是记住 他们的会议。因此，在主页以外的每个页面的顶部，您将在显示任何内容之前放置下面的代码（替换 pageUrl 中的URL以获取每个页面的实际URL ）：

This will appear seamless to the user, and will make it appear as if the web app is "remembering" their session. So at the top of every page other than the homepage, you would place the code below before any content is displayed (replacing the URL in pageUrl for the actual URL of each individual page):

<?php     
    $pageUrl = 'http://www.example.com/products/bicycles/';
    setcookie('lastPage', $pageUrl, time()+86400, '/');
?>

循环数据库结果：

<?php     
    foreach(database['row'] as $variableName => $variableValue) {
        setcookie($variableName, $variableValue, time()+86400, '/');
    }
?>
