Please help, I would like to get using PHP the get_id variable declared inside the javascript function.

<script>
     function confirmDialog (id, callback) {
        document.getElementById ("idConfirmDialogPrompt").innerHTML = id;
        confirmDialogCallback = callback;
        $("#idConfirmDialog").modal ("show");
        var get_id = id;
        }
</script>

          <?php echo "ID  : ". get_id ?>

</div>

Javascript is client side, PHP is server-side. PHP can give information to javascript, but javascript can't give information to PHP (directly).
