What you need is JavaScript. I suggest you use the jQuery framework as it eases the use of JavaScript.

You could do

$('#countries').change(function () { // bind the change event to your select input
    var country = $(this).val(); // retrieve the selected country
    $.get('fetch_states.php', {country: country}, function (res) { // using ajax, we retrieve the list of states/provinces associated with the country
        var states = res.split('\n'); // split the ajax result into spaces, assuming the php script placed LF between each state entry
        var html = ''; // create a buffer to handle the html
        for (var i = 0; i < states.length; i++) {
            html += '<option>' + states[i] + '</option>'; // append an option to the select
        }
        $('#states').html(html); // set the html buffer as the inner html of the #states select
    });
});

This assumes you have some sort of database which sorts all the info. Then a php script, in this case, fetch-states.php, fetches the states associated with the country.
You would need to do this again when the states select gets changed.
