PHP如何更快地執行這些檢查/或加快頁面加載？
[英]PHP How do I perform these checks faster/or load the page faster?
問題描述
我是PHP的新手，我想知道什么是更好的方法來執行此操作？ 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。 我實現它的方式很糟糕，因為如果你加載頁面，它會單獨檢查PHP中的每一個流，然后只顯示頁面和結果。 我的問題是，如何加載頁面a）更快或b）使用jquery或其他東西首先顯示頁面，但每個流它會說“正在加載...”，當它實際檢查它時，顯示結果喜歡它在下面。
這是提到的所有 PHP。

這是一個絕對最基本的例子，使用AJAX和jQuery
主頁上的jQuery：
$(document).ready( function() {
$("#stream1").load("stream1.php");
$("#stream2").load("stream2.php");
...
});
主頁上的HTML：
<div id="stream1">Loading...</div>
<div id="stream2">Loading...</div>
...
其中stream1.php ， stream2.php是使用您為每個流發布的代碼的文件。
考慮在jQuery中使用$ .ajax方法，並嘗試使其更具功能性。 應該讓你開始。

為了使速度更快，我建議保持腳本的運行方式並每5分鍾左右運行一次cronjob，並將在線離線用戶保存在本地數據庫中。 這將是最快的方式，因為查詢本地數據庫比依賴第三方站點響應更快。

您可以使用jQuery的ajax方法完成此操作 。 此方法有一個名為success的回調，您可以根據結果將“Loading ...”替換為“Online”或“Offline”。
