如何使用在線cPanel數據庫連接php中的動態數據庫

Question

在我的Web應用程序中，我有2個不同的連接：主連接和動態數據庫。我使用主連接來創建帶有表的新數據庫，並在用戶已經登錄時使用dynamic來切換數據庫。 。但是我的問題是當我將其更改為在線服務器cPanel時。 我無法登錄並連接到動態數據庫。 這是我的代碼如下：

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);
    }
}

在class.user.php中：

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');

            exit;

謝謝和前進。

您有來自特定提供商的托管服務，或者在線意味着什么？ 我有一個類似的問題，因為他們自己的設置不允許遠程訪問而沒有他們提到特定的IP（在我的情況下，我將Rasperry Pi作為應用程序的第二部分來推送數據）...並且設備必須已修復在這種情況下為IP，否則它將無法正常工作。
