jQuery ajax php函数

Question

I have never been in contact with ajax. Can I get some help?

I know how to call a php script.

Example:

<script>
        function myCall() {
            var request = $.ajax({
                url: "ajax.php",
                type: "GET",
                dataType: "html"
            });

            request.done(function(msg) {
                $("#mybox").html(msg);
            });

            request.fail(function(jqXHR, textStatus) {
                alert( "Request failed: " + textStatus );
            });
        }
    </script>

How can I get a response from function? If my ajax.php has function

<?php 

function example(){
  return "blablalba.....";
}
?>

How should my script looks like?

The PHP script just needs to display content as it would if you loaded it directly in the browser, using echo or simply closing your PHP tag ?> and outputting HTML or similar.
