What does the program print?

PHP

<?php

$name = 'Anna';
echo 'Hi, $name!', ' ', "Hi, $name!", ' ', "{$name}s", "\n";

Hi, $name! Hi, Anna! Annas

Expecting 'Hi, $name!' to show Anna: a single-quoted string is printed as typed, so $name stays the five characters $name.
Expecting the braces of {$name}s in the output: they only tell PHP where the variable name ends, and {$name} is replaced by the value as a whole.

What would "$names" print in this program, and why?
How do you print a dollar sign followed by the word name inside double quotes?
