How can the issue of needing to reload a page twice for a cookie to function be resolved in PHP?

Issue: The issue of needing to reload a page twice for a cookie to function in PHP can be resolved by ensuring that the cookie is set before any output is sent to the browser. This can be achieved by placing the setcookie() function at the very beginning of the PHP script, before any HTML or whitespace. 

<?php
// Set the cookie at the beginning of the script
setcookie('cookie_name', 'cookie_value', time() + 3600, '/');
// Rest of the PHP code and HTML content goes here
?>
