How can a Meta redirect 0 affect session generation in PHP?

A Meta redirect with a value of 0 can prevent the session from being generated in PHP because it immediately redirects the page before the session can be initialized. To solve this issue, you can disable the Meta redirect or delay the redirection until after the session has been started. 

<?php
// Start the session
session_start();

// Check if the session has been started
if(session_id() == '') {
    session_start();
}

// Delay the Meta redirect
header('refresh:5;url=redirected_page.php');
?>
