How can PHP developers ensure that form data is successfully passed using $_POST when implementing URL redirections?

When implementing URL redirections in PHP, developers should ensure that form data is successfully passed using $_POST by using session variables to temporarily store the form data before redirection. This way, the form data can be retrieved after the redirection and processed accordingly. 

<?php
session_start();

// Store form data in session variables
$_SESSION['form_data'] = $_POST;

// Redirect to another page
header("Location: another_page.php");
exit;
?>
