Joomla 5 cannot find standard PHP class Topic is solved

[kalinma]

I am upgrading an application to Joomla 5 and everything was fine until I started using namespaces. Now my component cannot find DOMDocument, a standard PHP class. It is trying to find the PHP class within my namespace. The error displayed is:

Class "My/Namespace/Path/Here/DOMDocument" not found

DOMDocument has been part of PHP since version 5. This is on my localhost with XAMPP on Windows 10. I'm running PHP 8.3.10, MariaDB 10.4.32 and Joomla 5.1.4. I have restarted apache and mysql several times with no success. How is it my component cannot find a standard PHP class and expects to find it within my namespace?

Prefix the class with a backslash or add "use" statement to import the class https://www.php.net/manual/en/language. ... orting.php

Thanks, Sharky. The backslash worked.
