PHP如何更快地执行这些检查/或更快地加载页面？

我是PHP的新手，我想知道什么是执行此操作的更好方法？ PHP使用own3d.tv和justin.tv提供的2个API来检查流的状态，无论它是在线还是离线。我实现它的方式非常糟糕，因为如果加载页面，它会逐个检查PHP中的每个流，然后仅显示页面和结果。我的问题是，如何加载页面或者a）更快或者b）使用jquery或者其他的东西来首先显示页面，但是通过每个流它会说“正在加载...”，并且当它被实际检查时，显示结果如下所示。PHP如何更快地执行这些检查/或更快地加载页面？

这里的所有中提到的PHP。

这可能更适合于[Codereview]（http://codereview.stackexchange.com） – Grexis 2012-02-11 10:40:29

如果您需要帮助，您需要更多解释 – 2012-02-11 10:41:17

这绝对是个最简单的例子，使用AJAX和jQuery

jQuery的主页上：

$(document).ready(function() { 
    $("#stream1").load("stream1.php"); 
    $("#stream2").load("stream2.php"); 
    ... 
});

HTML主页上：

<div id="stream1">Loading...</div> 
<div id="stream2">Loading...</div> 
...

凡stream1.php ，stream2.php是使用您为每个人发布的代码的文件al流。

考虑使用jQuery中的$就法并用的方式，使之更加实用玩了。应该让你开始。

感谢您的回复队友，此作品完美并且绝对可以在此之上工作！ – user1104783 2012-02-11 10:51:27

您可以通过使用jQuery的ajax method这样做。此方法有一个称为成功的回调，您可以根据结果将“加载...”替换为“在线”或“离线”。

为了使这甚至更快，我建议让你的脚本，它是如何运行一个cronjob每5分钟左右的时间，并保存线上线下的用户在本地数据库。这将是最快的方式，因为查询本地数据库比依赖第三方站点做出响应快得多。
