Is it recommended to store constant values in a MySQL database and retrieve them dynamically in PHP applications?

Storing constant values in a MySQL database and retrieving them dynamically in PHP applications can be useful for easily managing and updating these values without having to modify the code. However, it can introduce unnecessary overhead and complexity for values that truly are constant. It is generally recommended to use PHP constants or configuration files for storing constant values that do not need to be dynamically retrieved from a database. 

<?php

// Define constants in PHP
define('SITE_NAME', 'My Website');
define('MAX_UPLOAD_SIZE', 1048576); // 1MB

// Example usage of constants
echo SITE_NAME;
echo MAX_UPLOAD_SIZE;

?>
