Hi I have a web page that refreshes every 2 seconds for testing purpose. I want to write to a unique file each time I run the web page test.


I have this


if (!isset($_SESSION['current_file']))
    $file_name = "2-" . time() . ".txt";
    $_SESSION['current_file'] = $file_name;
When I echo this file na,e out it changes on each page refresh, but the session should be set after the first instance of the page.
