To set constant using `define()` will not work with `namespace` unlike using `const`.

Example:
<?php
namespace MyProject;

const IS_IT_CONNECTED = true; // will be able to access via `\MyProject\IS_IT_CONNECTED`

define('START_TIME', time());// will be able to access via `START_TIME` only, not be able to access via ---`\MyProject\START_TIME`---
?>

Call:
<?php
var_dump(\MyProject\IS_IT_CONNECTED);// true

var_dump(START_TIME);// numbers

var_dump(\MyProject\START_TIME);// Fatal error: Uncaught Error: Undefined constant...
?>
