How can I display values immediatly in my website? [closed]

  display, javascript, php, symfony

Im programming a web site in Symfony for football and I have to display the score immediatly on the page when he change.

So when the user will be in the page he doesn’t have to refresh to see the new score.

How can I do that please.
I think it’s in javascript but I don’t know the good method to do it.

( I’m sorry for my bad english)

Thank you !
