You can use constant in core php like this. 

define('SUPPORT_EMAIL', $support_email); 
echo SUPPORT_EMAIL;

In cakephp 3.x you can use constant like this.

In config/Bootstrap.php

$support_email = '[email protected]';
Configure::write('SUPPORT_EMAIL', $support_email);

In controller 

use Cake\Core\Configure; 

public function testcron(){

    $support_email = Configure::read('SUPPORT_EMAIL');
 }

In view file 

<?php use Cake\Core\Configure; 
$support_email = Configure::read('SUPPORT_EMAIL');
?>

You are getting this error because this contant is already defined somewhere. Either you can change the constant name or do the following

if (!defined('SUPPORT_EMAIL')) {
    $support_email = '[email protected]';
    define('SUPPORT_EMAIL', $support_email);
}

This will create constant only if it does not exist.
