mssql_connect(): Unable to connect to server
php, sql-server
Solution
You have to specify the servername and the instance like in this example,I think: https://www.php.net/manual/en/function.mssql-connect.php
EDIT: The following method: server\instance does'nt work on unix systems...
An instance is nothing more than specific port address different than 1433... so just discover the port on mssql server and then try to connect using:
ip:port
In unix the port is specified by : not by ,
Problem
I have a Centos server with apache and PHP on it, and I have a SQL Server on another server, when I try to connect to `MSSQL` with `tsql -H` "sql server ip" `-p1433 -U sa`, it works and connects OK, but when I try to run following `PHP` code ``` error_reporting(E_ALL); ini_set('display_errors', '1'); $connection = mssql_connect('serverIP', 'username', 'password'); ``` I get the error : Warning: mssql_connect(): Unable to connect to server: serverIP in /var/www/html/mssql.php on line 4 what should I do?
