I am using php 5.3.1 to connect to my SQL SERVER 2000 on remote machine. I use Windows XP.
On using simple program like this:
$conn = mssql_connect("VBNET","sa","mypass") or die ( 'Can not connect to server' );
I get following error:
Warning: mssql_connect() [function.mssql-connect]: message: Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection. (severity 14) in C:\wamp\www\Mssql\test.php on line 8
Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: VBNET in C:\wamp\www\Mssql\test.php on line 8
Can not connect to server
I enabled TCP/IP and named pipes in my SQL SERVER and restarted it. Also its Authentication is set to Mixed Mode Authentication.
I can see my server through MS SQL Server Management Studio. So what am I missing here ?
Thanks in advance.
P.S. I have another server in SQL SERVER 2008 to which I can easily connect with the same above mentioned connection string.
EDIT: According to this post, I fired sqlcmd -S np:\\VBNET\pipe\sql\query -U sa in cmd and entered the password and that worked !!! So now what could be the problem. I am at my wits end...please help !!
If you can connect using SSMS, then copy the connection exactly, i.e. make sure you specify a named instance (e.g. 'VBNET\SQLSERVER'). Open SSMS, on the server node on the left side right click and select 'Properties'.
If you have SQL 2008 running on the same machine it is most likely that SQL 2008 uses the default instance and SQL 2000 a named instance.
What also could help, i.e. make testing simpler is to create an empty UDL file (e.g. 'TEST.UDL'). An empty text file should do. Then double click on it, select the provider and play around with the settings. You can always test the connection using the 'Test connection' button. I use this trick when I have to connect from a customer PC for the first time.

I've read many questions similar to this but none of the answers have been relevant to me. I'm trying to access a SQL server using PHP. Both the SQL server and PHP are running on my Windows 10 machine. Here is my PHP code (the username and password are arbitrary):
$connection = mysqli_connect('127.0.0.1', 'hmuuser', 'password');
This causes the following error:
PHP Warning: mysqli_connect(): (HY000/2002): No connection could be made because the target machine actively refused it.
Here is my connection using MSSMS (which is successful):
EDIT:
I was able to solve my problem using this link: http://blog.citrix24.com/configure-sql-express-to-accept-remote-connections/
Using this link I enable SQL Browser, and set a static port to connect to SQL server with. However, I'm presented with a new error:
PHP Warning: mysqli_connect(): MySQL server has gone away in C:\HMUAPI\Index.php on line 7
PHP Warning: mysqli_connect(): Error while reading greeting packet. PID=9920 in C:\HMUAPI\Index.php on line 7
PHP Warning: mysqli_connect(): (HY000/2006): MySQL server has gone away in C:\HMUAPI\Index.php on line 7
My code has been changed to the following to cause this error: $connection = mysqli_connect('127.0.0.1:1434', 'hmuuser', 'password');
Add a database name
$connection = mysqli_connect('127.0.0.1', 'hmuuser', 'password','dbname');
Also here is suggest - Actively refused it" means that the host sent a reset instead of an ack when you tried to connect. It is therefore not a problem in your code. Either there is a firewall blocking the connection or the process that is hosting the service is not listening on that port. This may be because it is not running at all or because it is listening on a different port.
I guess the problem is, that you use MySQLi to connect to a MSSQL server.
You should use the correct MSSQL extension instead.
Microsoft published their SQL-Server for PHP driver on GitHub: https://github.com/Microsoft/msphpsql
Or you use the older extension which is documented in the PHP manual: http://de2.php.net/manual/en/book.mssql.php
And at least you can set up ODBC.
One of them should resolve your problem.
I just started learning PHP and MySQL, and I got stuck when trying to connect to my database from a PHP block. I have installed XAMPP and SQL Server Express 2012 on my machine. My server name is RAFAL-MAC and I selected 'Windows Authentication.'
I have a simple HTML page with PHP code in a file called search.php
the PHP code is
<?php
$con = mysql_connect('RAFAL-MAC','RAFAL-MAC\Rafal','');
if (!$con)
{
die( 'Could not connect: ' . mysql_error() ) ;
}
mysql_select_db("one", $con) or die(mysql_error());
?>
When I go to localhost:8080/search.php I get the following warning:
Warning: mysql_connect(): Host 'xxx.xxx.xxx.xxx' is not allowed to connect to this MySQL server in C:\xampp\htdocs\search_submit.php on line 11
Could not connect: Host 'xxx.xxx.xxx.xxx' is not allowed to connect to this MySQL server
I tried searching similar problems online, but all of the threads are about remote connections. I am just trying to connect to my local SQL server.
Any hints? I apologize for any missing information. Thanks! :)
EDIT:
I changed the server name to 'localhost'
Now I am getting this:
Access denied for user ''#'localhost' to database 'one'
Since you'd like to connect to SQL Server Express 2012, all functions beginning with mysql* will fail - since these functions speak to MySQL servers.
Please install Microsoft's MS SQL Server driver pack found here. From this page:
Perform the following steps to download and install the Microsoft
Drivers for PHP for SQL Server:
Download SQLSRV30.EXE to a temporary directory
Run SQLSRV30.EXE
When prompted, enter the path to the PHP extensions directory
After extracting the files, read the Installation section of the SQLSRV30_Readme.htm file for next steps
People in Microsoft's PHP driver forum should easily be able to answer your question, in case you still have problems after the installation of the driver.
Additionally, if connecting to the local machine, try to use these addresses:
localhost
127.0.0.1
These two addresses always reference the local machine.
I have been trying to connect to my SQL server from my web host using the built-in PHP functions, but no luck so far.
This is my code:
mssql_connect("201.252.95.27:1433/SQLEXPRESS", $sqlServerUsername, $sqlServerpassword);
And this is the error:
Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server
Tried using "201.252.95.27", "201.252.95.27:1433", "201.252.95.27,1433", "201.252.95.27:1433/SQLEXPRESS" and all possible combinations, but it isn't working.
The server is running and the port is open.
SQL Server usually uses a comma to separate the port, and a backslash to separate the instance name.
Using 201.252.95.27,1433\SQLEXPRESS I was able to connect to your server, but lacking a username/password, I couldnt log in.
I have found this question here and around internet for few times, but none answered helped me.
So I have a local apache+php server and trying to connect to remote mysql database. But script returns me error and in error log i see:
PHP Warning: mysql_connect(): Premature end of data (mysqlnd_wireprotocol.c:553) in D:\\_SERVER\\_WWW\\project\\api\\classes\\database.php on line 13
PHP Warning: mysql_connect(): OK packet 1 bytes shorter than expected in D:\\_SERVER\\_WWW\\project\\api\\classes\\database.php on line 13
PHP Warning: mysql_connect(): mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file in D:\\_SERVER\\_WWW\\project\\api\\classes\\database.php on line 13
The script for connection (just the part connecting to server):
function db_connect(){
// Connect to the database server
$connection = mysql_connect("server.com:3306","username","password",true);
if (!$connection){
echo "Could not connect to the Database server, please check your settings";
die;
}
...
}
The trick with setting PASSWORD did not work for me, can someone please help me ?
Thank you
The remote needs to allow incoming MySQL connections from your server's IP address. This can be added within a the MySQL config file from the remote server.
For more information in how to edit the config file, here are detailed instructions.
http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html
The firewall needs to port-forward to the server:port on the respective system,
which requires a static or dhcp address reservation for the mysql server machine
We are using MSSQL server 2008 on Win server 2008 R2 and have installed Apache (2.2.19) and PHP (5.2.17) separately. We have installd the MSSQL module for PHP and usingthe following connection string:
$myc = mssql_connect(Server, SiteDatabaseUsername, SiteDatabasePassword) or die('Can\'t connect to mssql Database Server: '.mssql_get_last_message($myc));
$db = mssql_select_db(SiteDatabaseName, $myc) or die('Can\'t find database: '.mssql_get_last_message($myc));
But it gives us this error:
Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: localhost\MSSQLSERVER in D:\Apache2.2\htdocs\adminarea\_core.php on line 89
Can't connect to mssql Database Server:
We have used the IP:PORT, localhost\MSSQLSERVER and COMPUTERNAME\MSSQLSERVER but don't seem to be getting anywhere, can anyone help please?
A few things come to mind:
1) Make sure you have the sqlsrv driver package from MS, and make sure you're loading it properly in php.ini (use phpinfo() to verify).
2) If this was a vanilla installation of SQL Server, its likely that only windows authentication is turned on. Open the SQL Enterprise Manager and make sure you have SQL Server Authentication enabled on your database.
3) Make sure that you have enabled network access to SQL Server. I'm not immediately certain whether the new MS drivers use named pipes to communicate with the server, or if they expect that the server will be accessed via the network.
These are the issues I routinely encounter when getting PHP speaking to a new MSSQL server.
