Question

我有一个PHP脚本来访问远程mysql数据库中的数据。脚本的重要部分是

$link = mysqli_connect("192.168.0.95", "user2", "passworduser2", "testDb", "3306")
    OR die ('Could not connect to MySQL: '.mysql_error()); 
@mysql_select_db (DB_NAME) 
    OR die ('Could not select the database" '.mysql_error());

我从本地机器运行：

user1@webserver: php accessmysqldatabase.php
    Could not select the database" Access denied for user 'user1'@'localhost' (using password: NO)

运行以下命令：

user1@webserver:~ $ mysql -u user2  -passworduser2   -h 192.168.0.95 testDb
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Welcome to the MySQL monitor.  Commands end with ; or \g.

所以这让我感到困惑，因为在第二个例子中，我获得了与远程机器的连接，但在第一个（php）中它拒绝运行PHP脚本的用户，而不是用户进行连接并声称连接是localhost

我可以在远程计算机上使用phpmyadmin使用user2和密码登录，没有任何问题。

任何人都可以解释什么是错误的。

谢谢

我没有看到代码的res，但我认为你应该用你的表名替换const DB_NAME
