What are some best practices for passing data between pages in PHP?

When passing data between pages in PHP, one common practice is to use sessions to store variables that need to be accessed across different pages. This ensures that the data is available throughout the user's session. Another approach is to use URL parameters to pass data through the URL. This method is useful for passing data between pages without the need for server-side storage. 

// Example of passing data using sessions
session_start();
$_SESSION['username'] = 'JohnDoe';
$_SESSION['email'] = 'johndoe@example.com';

// Example of passing data using URL parameters
// Page 1: sending data
$username = 'JaneDoe';
$email = 'janedoe@example.com';
header("Location: page2.php?username=$username&email=$email");

// Page 2: receiving data
$username = $_GET['username'];
$email = $_GET['email'];
echo "Username: $username, Email: $email";
