PHP如何更快地执行这些检查/或更快地加载页面？
问题描述：
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。

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。
