    You could use AJAX to send the country name to your PHP function.

    But you could also do it with Javascript like this if you do not need to determine the city dynamically from the server side.

        <script type="text/javascript">
        function sync() {
            var country = document.getElementById('country').value;
            var city = document.getElementById('city');
            switch (country) {
                case 'China':
                    city.value = 'Shanghai';
                    break;
                case 'France':
                    city.value = 'Pairs';
                    break;
            }
        }
    </script>

    <html>
        <form style="text-align:center">
            Country:<input id="country" type="text" title="Country" onblur="sync()"/><br/>
            City:<input id="city" type="text" title="City"/><br/>
        </form>
   </html>
