PHP如何更快地執行這些檢查/或更快地加載頁面？

我是PHP的新手，我想知道什麼是執行此操作的更好方法？ PHP使用own3d.tv和justin.tv提供的2個API來檢查流的狀態，無論它是在線還是離線。我實現它的方式非常糟糕，因爲如果加載頁面，它會逐個檢查PHP中的每個流，然後僅顯示頁面和結果。我的問題是，如何加載頁面或者a）更快或者b）使用jquery或者其他的東西來首先顯示頁面，但是通過每個流它會說「正在加載...」，並且當它被實際檢查時，顯示結果如下所示。PHP如何更快地執行這些檢查/或更快地加載頁面？

這裏的所有中提到的PHP。

這可能更適合於[Codereview]（http://codereview.stackexchange.com） – Grexis 2012-02-11 10:40:29

如果您需要幫助，您需要更多解釋 – 2012-02-11 10:41:17

這絕對是個最簡單的例子，使用AJAX和jQuery

jQuery的主頁上：

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

HTML主頁上：

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

凡stream1.php ，stream2.php是使用您爲每個人發佈的代碼的文件al流。

考慮使用jQuery中的$就法並用的方式，使之更加實用玩了。應該讓你開始。

感謝您的回覆隊友，此作品完美並且絕對可以在此之上工作！ – user1104783 2012-02-11 10:51:27

您可以通過使用jQuery的ajax method這樣做。此方法有一個稱爲成功的回調，您可以根據結果將「加載...」替換爲「在線」或「離線」。

爲了使這甚至更快，我建議讓你的腳本，它是如何運行一個cronjob每5分鐘左右的時間，並保存線上線下的用戶在本地數據庫。這將是最快的方式，因爲查詢本地數據庫比依賴第三方站點做出響應快得多。
