How can the blocking of cookies in browsers like Microsoft Edge affect PHP sessions and header redirects?

Blocking cookies in browsers like Microsoft Edge can affect PHP sessions because PHP sessions typically rely on cookies to store session IDs. If cookies are blocked, PHP sessions may not work as expected, leading to issues with session management and header redirects. To solve this issue, you can use URL-based session IDs in PHP by appending the session ID to URLs, ensuring that sessions can still be maintained even if cookies are blocked. 

<?php
session_start();

// Check if session ID is present in the URL
if(isset($_GET['PHPSESSID'])){
    session_id($_GET['PHPSESSID']);
}

// Continue with your code
?>
