How can PHP developers ensure that variable values are securely and efficiently passed between pages to maintain data integrity and user experience?

To ensure that variable values are securely and efficiently passed between pages in PHP, developers can use sessions to store and retrieve data. This helps maintain data integrity and improves the user experience by securely transferring information without exposing it in the URL. 

// Start a session to store and retrieve variable values
session_start();

// Set a variable value in one page
$_SESSION['variable_name'] = $variable_value;

// Retrieve the variable value in another page
$variable_value = $_SESSION['variable_name'];
