我如何停止AJAX调用以使PHP会话保持活动状态

&ajax=

然后，更改您的PHP会话代码：

session_start();if(!isset($_GET["ajax"])) $_SESSION["lastactivity"] = time();if(now() - $_SESSION["lastactivity"] > 3600){ //3600 seconds    header("Location: login.php?url="+urlenpre(str_replace("&ajax=", "", $_SERVER["REQUEST_URI"])));    //Example:    // Location: login.php?url=/sensible/secret.php?mode=show&hide=nothing    exit;}
