What are some best practices for handling cookie-related checks in PHP to avoid redirection loops?

When handling cookie-related checks in PHP to avoid redirection loops, it's important to ensure that the cookie check is performed before any redirection headers are sent. This can be achieved by placing the cookie check at the beginning of the script and using a conditional statement to redirect only if the necessary cookie is not set. 

<?php
// Check if the cookie is set
if (!isset($_COOKIE['example_cookie'])) {
    // Redirect to a different page
    header('Location: /login.php');
    exit;
}

// Rest of the script
// ...
?>
