Jeff,

The quick answer is, you can't. PHP is a server-side technology and therefore doesn't know about, or care about, signal's emitted by the browser once the HTML output has been sent by the server. You'd need to use a client-side technology like JavaScript to detect stuff like this. I'm sure something to this effect has already been written in Javascript, so a search on one of the JavaScript pages should give you what you need.

You cannot do it alone with PHP, but rather you have to combine php with JavaScript.

Conceptual model can be simple.

When somebody closes a window it triggers JavaScript interpreter to execute a function which might have a code like
function trigger_php()
{
window.location="http://www.mysite.com/php_script.php?m=1";
}

php_script.php could be the same page as the user has at the moment, meaning that no change will take place.

It is just an idea, but you can work with it to see what's the best way to do it. If it is too complicated, then think -> chances are you'll come up with a better solution - it always works like that!
