mysql — Как подключиться к динамической базе данных в php, используя онлайн базу данных cPanel

В моем веб-приложении у меня есть 2 разных соединения: основное соединение и динамическая база данных. Я использовал основное соединение для создания новой базы данных с таблицами, и я использовал динамическое переключение базы данных, когда пользователь уже вошел в систему. Я уже сделал это в localhost, он работает отлично . Но моя проблема, когда я изменяю его на онлайн-сервер cPanel. Я не могу войти и подключиться к динамической базе данных.
Вот мой код ниже:

create_database.php:

$curl_path = "";

function createDatabase($dbName, $dbUser, $dbPass,$userID,$userFullname,$userEmail,$userClinicname,$userAddress,$userCliniclogo,$username,$userpass) {

$cpanel_user = "name";
$cpanel_password = "pass";
$cpanel_host = "mocha3020.mochahost.com";
$cpanel_skin = "paper_lantern";

$db_name = $dbName;
$db_username = $dbUser;
$db_userpass = $dbPass;

$user_id = $userID;
$user_full_name = $userFullname;
$user_email = $userEmail;
$user_clinic_name = $userClinicname;
$user_address = $userAddress;
$user_clinic_logo = $userCliniclogo;
$user_name = $username;
$user_pass =$userpass;

$result = execCommand("http://$cpanel_user:$cpanel_password@$cpanel_host:2082/frontend/$cpanel_skin/sql/addb.html?db=$db_name");
// create user
$result .= execCommand("http://$cpanel_user:$cpanel_password@$cpanel_host:2082/frontend/$cpanel_skin/sql/adduser.html?user={$db_username}&pass={$db_userpass}");
// assign user to database

$result.= execCommand("http://$cpanel_user:$cpanel_password@$cpanel_host:2082/frontend/$cpanel_skin/sql/addusertodb.html?user={$cpanel_user}_{$db_username}&db={$cpanel_user}_{$db_name}&privileges=ALL");

include ('dynamicConfigs.php');
$DB_con = dynamicDatabase($db_username,$db_userpass,$db_name);
include('create_table.php');
}

function execCommand($command) {
global $curl_path;

if (!empty($curl_path)) {
return exec("$curl_path '$command'");
}

else {
return file_get_contents($command);
}
}

В class.user.php:

public function login($uname,$upass) {

try {
$stmt = $this->db->prepare("SELECT user_id, user_name, user_pass, user_clinic_name, db_username, db_pass FROM users WHERE user_name=:uname LIMIT 1");
$stmt->execute(array(':uname'=>$uname));
$userRow=$stmt->fetch(PDO::FETCH_ASSOC);
if($stmt->rowCount() > 0) {

if(password_verify($upass, $userRow['user_pass'])) {

if($userRow['user_Status'] != "Y"){
header('Location: index.php?inactive');
exit;
}

$_SESSION['user_session'] = $userRow['user_id'];
$_SESSION['username'] = $uname;

$registrationDate = date_format('Y-m-d');
$currentDate = new DateTime($registration_Date);
$editedcurrent = date_format($currentDate, 'Y-m-d');
$expDate = $userRow['expiration_Date'];

if ($expDate < $editedcurrent) {
header('Location:index.php?expiredUser');
exit;
}

$dbUsername = $userRow['user_name'];
$dbPassword = $userRow['user_pass'];
$dbName = $userRow['user_clinic_name'];
//update database
include('dynamicConfigs.php');
$DB_con = dynamicDatabase($uname,$upass,$dbName);

/*$random = password_hash(rand(1,20), PASSWORD_DEFAULT);
setcookie('logged_in' , $random, strtotime('+1 years'));
$stmt =  $this->db->prepare('UPDATE users  SET logged_in = 1, Cookie_Value = :cookie WHERE user_id = :user_id ');
$stmt->execute(array(':cookie' => $random, ':user_id'=> $userRow['user_id']));
$editedClinic = strtolower(str_replace(' ', '_', $userRow['user_clinic_name']));
*/
header('Location: Home.php');
}

else {
header('Location: index.php?error');
exit;
}
}

else {
header('Location: index.php?error');
exit;
}
}

catch(PDOException $e) {
echo $e->getMessage();
}
}

connection.php

$DB_host = "xxx.xx.xx.x2.";
$DB_user = "prophics_dentAid";
$DB_pass = "password";

}

catch(PDOException $e) {
echo "Connection failed: " . $e->getMessage();
}
}

index.php

require 'connection.php';
if (isset($_COOKIE['logged_in'])) {
$cookieValue = $_COOKIE['logged_in'];
$sth = $DB_con->prepare("SELECT user_id FROM users WHERE Cookie_Value =
:cookieValue " );
$sth->execute(array(':cookieValue' => $cookieValue));
$userRow=$sth->fetch(PDO::FETCH_ASSOC);
if ($userRow != "") {
$user -> checkCookies($userRow['user_id']);
exit;
}

else {
DisplayIndex();
}
}

else {

}

function DisplayIndex() {
require 'connection.php';
if(isset($_POST['btn-login'])) {

}

Спасибо и заранее.
