    In your browser use the network inspector to get the JSON response. In Chorme use the Response tab and copy the whole response. Paste it into https://jsonlint.com/ and you will find that it is not valid. The response as this at the end which makes it not valid:


    Take a look at this JSONP example. The response looks like this:

        "draw": 1,
        "recordsTotal": 57,
        "recordsFiltered": 57,
        "data": [
            ["Airi", "Satou", "Accountant", "Tokyo", "28th Nov 08", "$162,700"],

    I don't use PHP but if you look at the bottom of the script in teh Server-side Script tab you will see some additional code to handle the JSONP request. Looks like you might need to add that to your script.

    $('#example').dataTable( { "processing": true, "serverSide": true, "ajax": { "url": "server_processing.php", "dataType": json" } } );
