如何使用PHP连接到在线MySQL数据库? [英] How do I connect to an online MySQL database using PHP?
问题描述
我正在使用XAMPP离线测试网站.我的PHP代码连接到我的本地MySQL数据库并与之一起工作(即'localhost'或'127.0.0.1').我希望使用在线MySQL数据库进行测试. 我正在尝试使用PHPMyAdmin 演示服务器,但是尝试连接服务器时出现错误.我将"DB_HOST"更改为"192.168.30.23"(这似乎是演示服务器的IP地址).我想念什么吗?
I am testing a website offline with XAMPP. My PHP code connects and works with my local MySQL database (i.e. 'localhost' or '127.0.0.1'). I wish to conduct tests using an online MySQL database. I am trying to use PHPMyAdmin Demo Server but I get an error when trying to connect to the server. I changed the 'DB_HOST' to '192.168.30.23' (which seems to be the demo server ip address). Am I missing something?
这是我的代码段:
<?php
define('DB_NAME', 'ears');
define('DB_USER', 'root');
define('DB_PASSWORD', '');
define('DB_HOST', '192.168.30.23');
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if (!$link) {
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db(DB_NAME, $link);
if (!$db_selected) {
die('Can\'t use ' . DB_NAME . ': ' . mysql_error());
}
?>
谢谢.
推荐答案
phpMyAdmin MySQL演示服务器无法测试您的脚本.谷歌为公共访问MySQL服务器"找到了一个.
The phpMyAdmin MySQL demo server is not available to test your script. Google for "public access MySQL server" to maybe find one.
