What are the advantages and disadvantages of storing user input values as constants in a PHP script for a user interface?

Storing user input values as constants in a PHP script for a user interface can provide easy access to commonly used values throughout the script. However, it can also make it difficult to update or change these values later on. It is generally better to store user input values in variables or in a database for more flexibility. 

// Storing user input values as constants
define('USER_NAME', 'John Doe');
define('USER_EMAIL', 'johndoe@example.com');

echo 'Welcome, ' . USER_NAME . '! Your email is ' . USER_EMAIL;
