CodeIgniter - best place to declare global variable

Question

I just want to use a $variable at several places: not only views and controllers, but also in the routes.php and other configuration files.

Answer 1

The best place to declare global variable in codeigniter is the constants.php file in the directory /application/config

You can define your global variable as follows

/**
 * Custom definitions
 */
define('first_custom_variable', 'thisisit');
$yourglobalvariable = 'thisisimyglobalvariable';
