我想，当用户presses Facebook的Like按钮来更新数据库字段。

I want to update a database field when a user presses the Facebook Like button.

一个小片断低于我的code。我已经简化了，所以PLZ不启动有关的错误/不良行为;）

A small snippet of my code below. I've simplified it, so plz don't start about the errors/bad practices ;)

<?php
    function updateLike () {
        mysql_query("UPDATE like SET liked = '1'");
    }
?>

<script>
     FB.Event.subscribe('edge.create', function(response) {
         <?php updateLike() ?>
     });
</script>

所以，这是行不通的。我读过一些关于做一个AJAX调用，但我无法找到一个很好的例子，我的情况。

So, that doesn't work. I've read something about making an AJAX call but I couldn't find a good example for my situation.

谁可以把我在正确的方向？

Who can push me in the right direction?
