echo php variable with jquery ajax

I'm making my first website and I've encountered a problem with AJAX. I have tried and searched a lot of things but I'm missing something, please help me on this one. I have products' count and it works fine, but I need to refresh page everytime when I add new product to cart to see difference, so I need to use AJAX on my php variable. Please help me write AJAX code. I really appreciate it, thanks a lot and have a good day!

PHP Code:

<?php
 $cart = new cart(); 
 $products = $cart->getCart(); 
 $sum = 0; 
 foreach($products as $product){ 
     $sum += $product->count;
 } 
 echo $sum; 
?>

This can be done by adding the following code 

$.ajax({
                type: "GET",
                url: "your url",
                data: "",
                success: function () {
                        setInterval(functionName,timeInMilliseconds);                         
        }
  functionName=function(){
//your code comes here which you want to get refreshed
}

Using this code after a flag which will test with an if condition that the product count is updated or not. Cheers.

You could perform an ajax request like this. Your php will return the content which can then be appled to the DOM.

// create array to POST
aData = {
    AjaxRequest:true,
    PostField2:'content',
}


// perform ajax request 
$.ajax({
    type: "POST",
    url: "/relative_path_to_script/",
    data: aData,
    cache: false,
    success : function(data){
        console.log( 'response:' + data );
        $('#cartCountID').html(data);
    },

    failure : function(data){
        // report any ajax errors
    },

    complete : function(data){
        // runs once on completion
    }

});
