ajax but in php code example

Example 1: ajax php

$.ajax({
                type: "POST",
                url: "event.php", 
                data:"action=chnageChart&value1="+id,
                cache: false, 
                success: function(html){  
                    window.location.reload();
                }
            });

Example 2: ajax to php call

//Use $.ajax to call a server context (or URL, or whatever) to invoke a particular 'action'. What you want is something like:

$.ajax({ url: '/my/site',
         data: {action: 'test'},
         type: 'post',
         success: function(output) {
                      alert(output);
                  }
});
//On the server side, the action POST parameter should be read and the corresponding value should point to the method to invoke, e.g.:

if(isset($_POST['action']) && !empty($_POST['action'])) {
    $action = $_POST['action'];
    switch($action) {
        case 'test' : test();break;
        case 'blah' : blah();break;
        // ...etc...
    }
}
