Define URL in PHP File throw error in featured PHP Version

Question

I have a file called web.php inside that file I store code for define base URL address, assets folder.... File have next code:

<?php
    define('BASE', 'https://example.com/');
    define('ASSETS', BASE . 'assets/');
?>

So if we call function from above <?php echo BASE; ?>home.php i get error that says, check above.

All works fine but get an error that says, you need to change `BASE` it will throw an error in featured PHP Versions. I try to define different names, but same error. Can someone explain to me, how I can resolve this issue?

Answer 1

Im trying to repeat your Error

And as i see there no Errors at all

My PHP version is 7.4.3

<?php

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

define('BASE', 'https://example.com/');
define('ASSETS', BASE . 'assets/');

echo BASE;

echo "No errors";

Is it really php throw or may by it comes from your Framework?
