如何在javascript（Alertify.js）中包含php函数，这些函数已在php中回显

Question

我正在使用alertify.js库向用户提示cormfirmation。如果用户按下确定，它将运行某些PHP功能。警报是使用php回显的。但它会返回错误。

<?php
    include('header.php');

    if( isset($_GET['id']) && $_GET['action'] == 'delete'){
       $id = $_GET['id'];


            echo '<script type="text/javascript">
            alertify.confirm("Confirm Title", "Confirm Message", function(){ alertify.success("Ok")'.
                    if($user->deleteAccount($id)){
                           $_SESSION['current_url'] = $_SERVER['PHP_SELF'];



                 /*  echo "<script type='text/javascript'>
                               window.location.replace('clear_Post.php');
                    </script>";*/
           }
            .' }
                , function(){ alertify.error("Cancel")});
                   </script>';



   }
