php tags dont work in javascript for me

I'm trying to make a Control Panel for admins with a $_SESSION.
Now I have created a javascript controlled button that asks to terminate the current session, and that will make it to delete the $_SESSION ((unset it)).

I have used this javascript code:

JavaScript

<script type="text/javascript">function Test() {
		var _endSession = confirm("End current editing session ?");
		if(_endSession == true)
		{
			<?php
				unset($_SESSION['."'UsernameChosen'".');
			?>
			alert("Session terminated.");
		}
		else
		{
			alert("Session active.");
		}
	}</script>

If I remove the tag, it'll work with only the alerts.
But if I remove the unset it still wouldn't work. So I just assumed that the php tags in javascript aren't functioning right, did I do anything wrong or is php isn't workable in javascript ? If it isn't how could I do this function script ?

you cannot use like this the correct way is

JavaScript

<script type="text/javascript">function Test() {
		var _endSession = confirm("End current editing session ?");
		if(_endSession == true)
		{
                      
							unset($_SESSION['."'UsernameChosen'".');
			?>
                       <script>
			alert("Session terminated.");
		}
		else
		{
			alert("Session active.");
		}
	}</script>
