I installed the Symfony skeleton and I am running with the integrated development server. I am using Ubuntu.
When I go to src/Controller and create the file ArticleController.php I get the error LogicException Extension DOM is required.
I even tried to install PHP-XML and my system shows that it is already installed.
This is the output that I get

I am trying to learn Symfony and was taking a course from YouTube to learn how it works. So I am a newbie with Symfony. Any help would be appreciated.
For some reason I only get this error when I run the symfony app via the integrated server it comes with. But when I run it from my LAMPP stack, and I place the symfony application within my Apache, the error goes away.
I am not sure why that is happening, but I guess I will just use it like this.

EDIT:
composer require ext-dom within the project folder did the trick!
Farhang gave me the solution. I appreciate it.
