use ajax like that :-

$.post('file.php', {variable: variableToSend});

code like that :-

    <script type="application/javascript">
    $(document).ready(function(){$('select[name="dropdown"]').change(function(){

        var a=$(this).val() ;
        $.post('file.php', {variable: a});
    });
});

On your server, you would need to receive the variable sent in the post:

$variable = $_POST['variable'];
