You can do it with PHP:
header("Refresh:0");
It refreshes your current page, and if you need to redirect it to another page, use following:
header("Refresh:0; url=page2.php");
In PHP you can use:
$page = $_SERVER['PHP_SELF'];$sec = "10";header("Refresh: $sec; url=$page");
Or just use JavaScript's window.location.reload().
window.location.reload()
You sure can refresh a page periodically using PHP:
<?php header("refresh: 3;");?>
This will refresh the page every three seconds.
