• 2 The only wany I know to send data to php from js is AJAX – Emilio Gort Commented Oct 3, 2013 at 0:55
• 3 Why do so many people seem to think you can just call PHP functions in JavaScript...? – Niet the Dark Absol Commented Oct 3, 2013 at 0:56
• 3 WHat you are doing here could possibly cause an irreversible rip in the time-space fabric. Try doing some research on AJAX and how to use it with PHP and Javascript. – DevlshOne Commented Oct 3, 2013 at 0:57

You need to use AJAX, it's easy with jQuery or another library, so I'll demonstrate with jQuery.

javascript

var deleteClient = function(id) {
    $.ajax({
        url: 'path/to/php/file',
        type: 'POST',
        data: {id:id},
        success: function(data) {
            console.log(data); // Inspect this in your console
        }
    });
};

php file

<?php

    if (isset($_POST['id'])) {

        deleteClient11($_POST['id']);

        function deleteClient11($x) {
           // your business logic
        }

    }

?>
