Perintah MySqli tidak sinkron; Anda tidak dapat menjalankan perintah ini sekarang

Jika Anda membuat variabel untuk kueri dan menempelkan variabel secara langsung ke sesuatu seperti MySQL Workbench, Anda dapat memeriksa sintaks sebelum dieksekusi.

<?php
            function myConnection(){
              $myConnection = mysqli_connect('localhost', 'my_user', 'my_password', 'my_db');
              return $myConnection;
            }   


    function register_user($register_data) { 
        array_walk($register_data, 'array_sanitize'); 
        //Make the array readable and seperate the fields from data 
        $fields = '`' . implode('`, `', array_keys($register_data)) . '`'; 
        $data = "'" . implode("', '", $register_data) . "'"; 
        //Insert the data and email an activation email to the user 
        $query = "INSERT INTO `members` ($fields) VALUES ($data)";
                    $myNewConnection = myConnection();          

                    if($result = mysqli_query($myNewConnection, $query)){ 
        email($register_data['mem_email'], 'Activate your account', "Hello " . $register_data['mem_first_name'] . ",\n\nThank you for creating an account with H Fencing.
