PHP runs when not supposed to in javascript

I have the following code in php:

PHP

echo '<head><script type="text/javascript">function EndSession() {
		var _endSession = confirm("End current editing session ?");
		if(_endSession == true)
		{';
				unset($_SESSION['UsernameC']);
			echo 'alert("Session terminated.");
			window.location = "index.php?page=acp";
		}
		else
		{
			alert("Session active.");
		}
	}</script></head>';

You can notice the ' unset($_SESSION['UsernameC']); ' is part of the php script, that ment to run only inside the javascript, but it runs anytime, is there any way to fix it ?

PHP

unset($_SESSION['UsernameC']);

This is server-side code, and will run when the page is being "rendered" in server to be sent to the client.

Your javascript runs in the client side, that don't have direct access to the server-side code.

Maybe you could create a logout page that remove the user session and then redirects him to the index page or you could do the session logout through an Ajax call.

What you need to have in mind is:

PHP -> server-side code

javascript -> client-side code

and that client and server code don't have direct access to each other.

Hope it helps.
