IIS无法连接到远程数据库

Question

I have a website on IIS and want to access a database on a remote host.

my code:

$this->db = new mysqli($hostname, $username, $password, $dbname);

I get this error:

Es konnte keine Verbindung hergestellt werden, da der Zielcomputer die Verbindung verweigerte

In english its like

Remote Host refused connection

Default Port is 3306, when I execute

$this->db = new mysqli($hostname, $username, $password, $dbname, 3306);

I get the same result.

Via cmd telnet I can't connect to $hostname 3306, but to $hostname 1433.

So I tried

$this->db = new mysqli($hostname, $username, $password, $dbname, 1433);

But this isn't working either. I get

mysqli::__construct(): MySQL server has gone away

mysqli::__construct(): Error while reading greeting packet. PID=3276

Do you know how I can get the connection to the database?

Answer 1

Based on the info in your question, it looks like the remote database is SQL Server, not MySQL. Therefore you need to use PHP's MSSQL library: http://php.net/manual/en/book.mssql.php

It usually requires additional installation/configuration though.
