What are the best practices for handling form submissions and data transmission in PHP to avoid losing data during redirection?

When handling form submissions and data transmission in PHP, it's important to use sessions to store form data temporarily before redirecting the user. This ensures that the data is not lost during redirection. By storing form data in sessions, you can retrieve it on the redirected page and process it accordingly. 

<?php
session_start();

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Store form data in session
    $_SESSION['form_data'] = $_POST;

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

// Retrieve form data from session on redirected page
session_start();
if(isset($_SESSION['form_data'])) {
    $form_data = $_SESSION['form_data'];
    // Process form data as needed
}
?>
