What are some best practices for handling form submissions and data transfer between PHP pages?

When handling form submissions and data transfer between PHP pages, it is important to sanitize and validate user input to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. Additionally, using PHP sessions or cookies to store and transfer data between pages can help maintain user state and improve user experience. 

// Example of handling form submission and data transfer between PHP pages

// Sanitize and validate user input from form submission
$name = htmlspecialchars($_POST['name']);
$email = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL);

// Store validated data in session for transfer to another page
session_start();
$_SESSION['name'] = $name;
$_SESSION['email'] = $email;

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