                  问题描述

                  我知道有很多这样的问题,但我没有找到任何解决方案.

                  I know there are many questions like this, but i didn't find any solution in it.

                  我尝试过的事情:-

                  • 检查防火墙

                  • checked firewall

                  重新启动我的电脑和 Apache 服务器

                  restarted my PC and Apache server

                  重启MYSQL

                  检查了我的代码

                  尝试了我在互联网上所知道和找到的一切

                  Tried everything i know and found on internet

                  这是我的代码:-

                  <?php
                  
                  $dbhost = 'localhost:3360';
                  $dbuser = 'root';
                  $dbpass = '';
                  $db     = 'test_db13';
                  
                  
                  $conn  = mysqli_connect($dbhost,$dbuser,'',$db);
                  
                  if(! $conn){
                    die('Could not connect connect: ') ;
                  }
                  
                  echo 'Successfully Connected';
                  
                  
                  $sql = 'Connected Successfully';
                    $retvalue = mysqli_query($sql);
                  
                    if(! $retvalue){
                      die('Cannot connect to SQL: ');
                    }
                  
                  echo 'DataBase test_db13 has successfully created';
                  
                  mysqli_close($conn);
                  
                   ?>
                  

                  我确实设置了密码,但它仍然显示错误.

                  I did set the password, but it still is showing me the error.

                  XAMMP 终于运行了,这就是证明

                  lastly XAMMP is running here's the proof

                  推荐答案

                  如果你查看你的 XAMPP 控制面板,它清楚地表明 MySQL 服务器的端口是 3306 - 你提供了 3360.3306 是默认值,因此不需要指定.即便如此,mysqli_connect() 的第 5 个参数是端口,也就是应该指定的地方.

                  If you look at your XAMPP Control Panel, it's clearly stated that the port to the MySQL server is 3306 - you provided 3360. The 3306 is default, and thus doesn't need to be specified. Even so, the 5th parameter of mysqli_connect() is the port, which is where it should be specified.

                  您可以完全删除端口规范,因为您使用的是默认端口,使其成为

                  You could just remove the port specification altogether, as you're using the default port, making it

                  $dbhost = 'localhost';
                  $dbuser = 'root';
                  $dbpass = '';
                  $db     = 'test_db13';
