How to output all records from a mysql column?

Question

PHP

I'm just starting to understand php, I don't quite understand how to display all records from one column, there is a piece of code that should get and display records from this column from the database, namely the name of those who are there, but for some reason it displays only one record from the column , maybe I didn’t add something?

$result=DB::query("SELECT * FROM `mg_hoax` order by `fio`");
$user_new = $result->fetch_assoc();

echo $user_new;

Outcome: Ivanov Ivan Ivanovich1 (there are three of them in the column)
What should be added so that all names are displayed?
