IntlDateFormatter gregorian calendar

When I create a new instance of IntlDateFormatter in the controller I get this error:

Error
Class 'App\Controllers\Panel\Articles\IntlDateFormatter' not found

Is there anyway to use IntlDateFormatter class in CI4 ?

I assume you wish to use PHP's IntlDateFormatter class?

Based on that error message it appears PHP is looking in the wrong namespace. Try adding a "use" clause to the file being executted.

PHP Code:

use IntlDateFormatter; 


This will let PHP know that the class is in the "root" PHP namespace.
