Custom likes counter with jquery

I want to make a custom likes counter. For this I have used the following code:

var likes = 0;
$('#button').click(function(){
      likes += 1;
      $('#likes').text(likes); //A <p id="likes"> html tag created before
      window.stop(likes);
});

The problem is the scope of this function. I need to use the "likes" variable outside the scope to convert it to a php variable and save that value in my mysql database. I've tried several ways, but it has not worked for me. Any suggestions?

You just need the ajax part to save it

var likes = 0;
$('#button').click(function(){
    likes += 1;

    $.ajax({
        type: "POST", 
        url: "/save.php", 
        data: "likes="+likes, 
        success: function(returnMsg){ 
          $('#likes').text(likes);
          window.stop(likes);
        }
    });
});

As for the PHP well the var will be $_POST['likes'] use it to save it
