What are the potential issues with using header('location:'.$_SERVER['PHP_SELF']); to reload a page in PHP?

Using header('location:'.$_SERVER['PHP_SELF']); to reload a page in PHP can potentially cause a redirect loop if the page is accessed via a different URL. To solve this issue, you can use header('Refresh:0'); instead, which will reload the current page without causing a redirect loop. 

<?php
header('Refresh:0');
?>
