第二列，在程序中，它说没有记录。不应该是这样的。那里的结果来自另一个数据库的数据。我已经有了它的代码，如果我将包含与另一个 mysql_connect 配置（来自另一个数据库）的不同 php 文件一起使用，则不会像这里看到的那样检索患者信息：

我知道如何通过存储两个连接的不同变量来进行多个连接。但它让我很困惑，因为它在不同的包含文件中。

屏幕截图中的那个页面是editclient.php我editclient_include_inv.php在“程序”部分的代码中包含的。

您尚未发布任何代码，但从您的问题文本中，我可以看到您正在使用mysql_connect()连接到数据库。

这里首先要学习的是不要使用mysql_xxx()函数。这有很多原因——首先，它们已被弃用，而且它们也不安全。

您应该使用 PHP 中内置的另外两个 API：要么mysqli要么PDO.

但在这种情况下，不使用这些函数的更好理由mysql是它们使管理多个数据库连接变得更加困难。

另一方面，使用mysqli或管理多个数据库连接PDO非常容易。

$db1 = new PDO('mysql:host=xxxxx,etc',$user1,$pass1);
$db2 = new PDO('mysql:host=xxxxx,etc',$user2,$pass2);

$db1->query('SELECT * FROM table_on_db1');
$db2->query('SELECT * FROM table_on_db2');

因此，您可以根据需要保持尽可能多的连接对象处于活动状态，并且只使用适合任何给定查询的连接对象。

您可以在此处了解有关 mysqli API 的更多信息：http ://www.php.net/manual/en/book.mysqli.php

关于这里的 PDO API：http: //php.net/manual/en/book.pdo.php

希望有帮助。

mysql_connect()返回您需要存储的连接标识符，然后传递给您的所有 mysql_* 函数。这就是每个脚本维护多个数据库连接的方式。

但是，mysql_* 函数已被弃用，您应该迁移到 PDO 或 mySQLi。这将有一个额外的好处，即允许您初始化和存储单独的数据库对象，而不是跟踪连接标识符。IE：

$db1 = new PDO('mysql:host=host1;dbname=db1', $user1, $pass1);
$db2 = new PDO('mysql:host=host2;dbname=db2', $user2, $pass2);
