How can PHP variables be made consistent to prevent reinitialization when the script is called again?

To prevent reinitialization of PHP variables when the script is called again, you can use session variables to store the values persistently across different script executions. By storing the variables in the session, you can ensure that their values remain consistent throughout the user's session. 

<?php
session_start();

if (!isset($_SESSION['my_variable'])) {
    $_SESSION['my_variable'] = 'initial_value';
}

// Now you can use $_SESSION['my_variable'] throughout your script without fear of reinitialization
?>
