A simple method for PHP to prevent session expiration

Recently some users have reported their hard work It’s really frustrating to click submit after working on an article for several hours, only to be told that you need to log in again. I think this is probably because the session has expired. So I used js timer to solve this problem.

The js code is as follows:

setInterval( function(){jQuery.get("/plugin.php?id=xxxxxx:refresh",function(data,status){});} , 2000);

In fact, there is no need to execute it every two seconds, just fifteen minutes. To prevent browser caching, you can add a random parameter after the path.

The code in the php page executed is as follows:

<?php
    echo $_SESSION[&#39;refresh&#39;] = rand();
?>
