I have a page that needs to be constantly refreshed multiple times a minute. The page has is a echo'd php table.

The page loads perfectly fine, all is good, I have used the META tag HTML, I have used the header tag with the refresh function in PHP... and yet a problem arises :
页面加载得很好，一切都很好，我使用了 META 标记 HTML，我使用了带有刷新功能的页眉标记在 PHP 中......但出现了一个问题：
When I hit Start Session button the refresh stops. And the table bellow does does not get updated. So then I have to manually refresh the page. This is not the desired affect. Can some one explain to me how to refresh a page continually.
当我点击开始会话按钮时，刷新停止。并且下表不会更新。那么我必须手动刷新页面。这不是想要的效果。有人可以向我解释如何不断刷新页面。

If you are looking to refresh the page when you click "Start Session", then you can edit your submit button to have this onClick listener. It should refresh the page.
如果您希望在单击“开始会话”时刷新页面，那么您可以编辑您的提交按钮以使用此 onClick 侦听器。它应该刷新页面。
<input type='submit' name='submit' value='Start Session' onClick="window.location.reload()" />

Is it possible for you to use Javascript to achieve the desired effect? I don't know enough about what you're doing to determine whether that would clear your changes or not (my assumption here is: no).
是否可以使用Javascript来达到想要的效果？我不太了解您正在做什么，无法确定这是否会清除您的更改（我的假设是：否）。
If you are able to use Javascript, you could write a simple function which refreshes the page on an interval.
如果您能够使用 Javascript，您可以编写一个简单的函数来每隔一段时间刷新页面。
