php - 阅读问候包时如何解决错误？

Question

我正在尝试连接到 NetBeans 中的服务器。 我写的代码如下:

<?php
echo "wlecome";
echo "<br>";

$conn=mysqli_connect("mydomain.com:2082", "phpmyadmin_user", "password","database_name");
                     
echo $conn;
?>

运行此代码会返回此错误:

wlecome

出于安全原因，MySQL 可以配置为不接受外部连接。通过说完整的域名，您使用的是公网 IP，因此您是外部连接。如果 MySQL 与您的网络服务器运行在同一个机器上，只需通过此域名访问它:

localhost:2082
