How to Refresh a Page Periodically Using PHP

Use the header() Function

You can simply use the header() function to automatically refresh a page periodically (i.e. at certain time intervals) using PHP. Please, note that header() function must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP script.

The following example will refreshes the current page every five seconds.

<?php
header("refresh: 5;");
?>
