mysqli :: __ construct（）期望参数5为整数

I am trying to upload my website to a web hosting but i need phpmyadmin so i went to phpmyadmin.co with the username, password and server then when i tried to add that to my php file it came up with this error

mysqli::__construct() expects parameter 5 to be integer

this is the code of my website

<?php

class User{
private $dbServer   = "";
private $dbHost     = "http://www.phpmyadmin.co/";
private $dbUsername = "";
private $dbPassword = "";
private $dbName     = "sql12168044";
private $userTbl    = "users";

public function __construct(){
    if(!isset($this->db)){
        // Connect to the database
        $conn = new mysqli($this->dbHost, $this->dbServer, $this->dbUsername, $this->dbPassword, $this->dbName);
        if($conn->connect_error){
            die("Failed to connect with MySQL: " . $conn->connect_error);
        }else{
            $this->db = $conn;
        }
    }
}

You are passing the fifth parameter of the mysqli object as the $dbName, but that should be the $dbPort which is optional, and must be an integer. You have to reorganize your parameters to match this:

mysqli::__construct ([ string $host = ini_get("mysqli.default_host") [,string $username = ini_get("mysqli.default_user") [, string $passwd = ini_get("mysqli.default_pw") [, string $dbname = "" [, int $port = ini_get("mysqli.default_port") [, string $socket = ini_get("mysqli.default_socket") ]]]]]] )

In order: $host, $username, $passwd, $dbname and $port. I don't see any room there for your $dbserver.

UPDATE:

Just use this:

public function __construct(){
    if(!isset($this->db)){
        // Connect to the database
        $conn = new mysqli($this->dbHost, $this->dbUsername, $this->dbPassword, $this->dbName);
        if($conn->connect_error){
            die("Failed to connect with MySQL: " . $conn->connect_error);
        }else{
            $this->db = $conn;
        }
    }
}

And get rid of that $dbServer.
