php mssql_connect: failed - php

I am moving data from a MSSQL database to a MySQL database. I need to connect with PHP to MSSQL and then insert into MySQL. Could someone tell me how to:
See if the mssql server is running remotely,
How to connect to it?
Code:
mssql_connect($host,$user,$pass) or die('Failed Server Connect! ' . mssql_get_last_message());
mssql_select_db($dbnm) or die('Failed DB Select!');
Note: The webserver and db are on separate machines but mysql and mssql are are the same db machine.
I change to:
$dsnn = "Driver={SQL Server};Server={$host};Database={$dbnm}";
// Connect to the data source and get a handle for that connection.
$conn=odbc_connect($dsnn,$user,$pass);
I successfully figured out the Source issue and could not find db issue but now getting:
I now have a message saying: Login failed for user "xxx".
Figured it out. Was told the wrong password. Reset and now works.

try **Telnet <IP Address> <Port Number>** ? Is any error shown?

Since you are running PHP on Windows, have you considered trying out the SqlServer driver for PHP? Where I work, we are using it on one of our projects, and have had wonderful results with it.

Connecting to MySQL database in XAMPP on Mac

I am using cakePHP to connect to a database in XAMPP phpMyAdmin. I have added a new user, set the password and set the privilleges. I cannot for the life me create a connection to the database on my localhost. What I have done so far.... I have a live web server with a database. I can connect to this database no problem. I have a database running in MySQL workbench on localhost. I can connect to this no problem. This tells me that there is nothing wrong with my connection code and the problem must sit with phpMyAdmin in XAMPP. I have created a simple connection PHP script to try and connect to the database and it doesn't work. The same script can connect to my live web server and my localhost MySQL workbench database but not my XAMPP database. My connection script is as follows:
<?php
$con= mysqli_connect("localhost","root","","test");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
// Perform a query, check for error
if (!mysqli_query($con,"INSERT INTO Persons (FirstName) VALUES ('Glenn')"))
{
echo("Error description: " . mysqli_error($con));
}
mysqli_close($con);
?>
The error message I get is;
Failed to connect to MySQL: Access denied for user 'root'#'localhost' (using password: NO)Error description:
If i go to phpMyAdmin in XAMPP and go to the test database I can clearly see that this user has full access. I have tried using the host name as 127.0.0.1, localhost and ::1. Nothing seems to work. I just dont understand why XAMPP will not let me connect to the database. I hope I'm not missing something obvious so any help will really be appreciated. here is a screen shot of the users and their privilleges for the database test
That's the second reason why one should never use 'root' unless one knows exactly what one is doing. Only a few expirenced ones really know what they're doing each and every moment...
Add a specific useraccount like 'data' on your localhost and grant it the needed priviledges on your DB.
I am actually using the username 'login' with an auto generated password that is of high complexity. This however doesn't work either. I have used the 'root' user with no password to highlight the fact that not even the admin accounts can connect.
Open config.inc.php file in the phpmyadmin directory
Find line 21: $cfg['Servers'][$i]['password'] = '';
Change it to: $cfg['Servers'][$i]['password'] = 'your_password';
Restart XAMPP

phpMyAdmin refuses MYSQL connection - How to fix it?

I'm creating a web application in PHP and I need to connect to a database and retrieve information from it. The database in question is being hosted on phpMyAdmin. I'm currently using the following PHP code to connect to it.
//Attempt to connect to the database
$conn = mysql_connect('localhost', 'my_username', 'my_password') or die (mysql_error());
//Tell the user if they were successful
echo "Connection successful!";
//Close the connection
mysql_close();
When I run the website, it produces the following SQL error:
"No connection could be made because the target machine actively refused it."
I'm sure that my username and password are spelled correctly and I believe that 'localhost' is the server name that I need to use. Is there a different mysql_connect command that I need to use for phpMyAdmin? If not, how can I solve this problem?
Edit:
Upon publishing the website to Microsoft Azure (where I need to host it), I've found that it produces a different error:
"An attempt was made to access a socket in a way forbidden by its access permissions."
How will I be able to fix this error? Or will fixing the original error also solve this one?
Do not use mysql_* functions. They are deprecated. For more information, see this question: Why shouldn't I use mysql_* functions in PHP?
phpMyAdmin hosts nothing; it is simply a PHP application that connects to your database just like your own app is attempting to do.
Take a look at the phpMyAdmin config file and ensure you are using the same host. Also try the same username/password. If this succeeds, it's advisable to set up a dedicated username/password for your application. This can be done within phpMyAdmin on the privileges page.
Try use IP instead of localhost.
User has permissions? Check them

Setting up a local call to DB with an online PHP file - trouble connecting

Trying to figure out how to connect to a local SQL Server with an online PHP file. However I am getting connection errors.
Warning: mysql_connect() [function.mysql-connect]: [2002] No
connection could be made because the target machine actively refused
it. (trying to connect via tcp://localhost:xxxx) in
E:\web\example.com\uploads\readDB.php on line 8
In particular I am having trouble trying to specify if, and where, I do the connection to the PC and then to the database with any associated passwords.
My current connection looks like this
mysql_connect("localhost","the_sql_server_name\SQLEXPRESS","mysql");
mysql_select_db("ACME") or die(mysql_error());
$data = mysql_query("SELECT * FROM TradingAccount")
or die(mysql_error());
My server is run locally (sql server studio management 2012), and I am trying to connect to its specific DB called ACME, from the table TradingAccount.
Can someone show me how to connect to this local table successfully with PHP? I use Windows Authentication at the moment when I run the server as well, in case that matters.
I haven't been able to find any useful resources, and I have only ever used PHP to connect to online DB's as well, nothing locally before.
Your Problem is in this line:
mysql_connect("localhost","the_sql_server_name\SQLEXPRESS","mysql");
You wrote the_sql_server_name\SQLEXPRESS there. I don't understand why. The syntax of the method is:
mysql_connect("hostname", "username", "password");
For more information, visit the PHP manual entry for mysql_connect.

PHP 5.3 Upgrade - Can't Connect to MySQL Server

I've done a bit of research on this today, but nothing seems to address this issue. I recently upgraded to PHP 5.3.3 from 5.1.6, as well as upgraded MySQL to 5.5 from 5.0. Afterwards, the following code generates an error saying "Can't connect to mysql database":
$connection = mysql_pconnect($dbhost, $dbusername, $dbpassword);
if (!$connection) {
//Can't connect
die('Could not connect: ' . mysql_error());
return;
}
And get the following error:
Warning: mysql_pconnect(): Can't connect to MySQL server on '199.59.157.103' (13) in /var/www/html/ws/Cust/customerWS_1_1.php on line 19 Could not connect: Can't connect to MySQL server on '199.59.157.103' (13)
I am able to connect to the remote host via the command line, and have tried everything from resetting the password to shutting down IP Tables. I'm kind of at a loss - so any help would be appreciated.
We had a similar problem with the same error message "Can't connect to mysql database" and maybe the following points will be also usefull:
check mysql user privileges (in our case and with external connections we had the old server IP address (allow access) in the table) GRANT ALL PRIVILEGES ON tablename.* TO 'username'#'145.1.1.2';
-> reload privileges after changes (FLUSH PRIVILEGES;)
disable the SELinux parameter. In new Plesk versions (>10?) this would be set enabled automatically...
--> in /etc/selinux/config change the line that says:
SELINUX=enforcing to SELINUX=disabled
See further details: http://googolflex.com/?p=482
There is a PHP 5.3 mysql driver restriction related to old authentication scheme hash stored in the database by previous mysql server. This could cause a problem with stored passwords so the databases will be unaccessible with old passwords.
To solve the problem you should recreate the mysql users with the same login and same password.
When you say "I am able to connect to the remote host via the command line" do you mean, you are connecting to the MySQL server REMOTELY? Or that you are SSHing to your MySQL server and connecting to it from the MySQL server's command line? If the latter, it's possible that when you upgraded to MySQL 5.5 you accidentally stopped MySQL from binding / listening on a public IP. Check your my.cnf.
Otherwise: is your PHP code being run on the same server as your MySQL server? It's possible that your permissions could be off. MySQL permissions are very particular about connecting to the MySQL server via it's IP address if the client only has access to connect from 'localhost', and vice-versa.
First you should make sure that the connect parameters $dbhost, $dbusername and $dbpassword are correct. Assuming these are correct, you should check your mysql ini settings. I would assume that the bind-address is set to 127.0.0.1 or localhost, but not to a public IP address.
Also note that it's a security risk if you can connect to mysql from a public IP address. You may want to look into a solution that does not require such connection.

Trouble connecting to SQL Server with PHP

I'm trying to connect to my local SQL Server 2008 R2 (have also tried it with 2005, same result exactly) with PHP. I'm using PHP 5.1 which still supports php_mssql and mssql_connect().
for some reason PHP just won't find my server, I can connect via ODBC flawlessly an that's fine, but I would like to connect to SQL Server directly.
I have connected PHP to SQL Server a million times on different servers, this one seems to be the only one giving me issue.
This is my little test code to try and get the connection working.
//define connection garbage
$db['hostname'] = "USER90C6\SQLEXPRESS";
$db['username'] = "user";
$db['password'] = "password";
$db['database'] = "kal_auth";
//connection string
$conn = mssql_connect($db['hostname'], $db['username'], $db['password']);
//does it work? :o
if($conn)
{
echo "works";
}
else
{
echo "fails";
}
The error this code produces:
Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: USER90C6\SQLEXPRESS in C:\xampp\htdocs\test.php on line 9
fails
Is there something seriously wrong with my setup? or am I missing something.
Did you enable TCP/IP on the server's configuration tool?
Is the firewall blocking any ports you might be using?
Are your MDAC (microsoft data access components) updated?
turn on mssql.secure_connection in php.ini
I think you don't miss anything.. Your connection string seems to be right (you receive a "Unable to connect" error..).
In my opinion, you problem can be a version incompatibility or a user privileges mistake. First of all: look at DLL driver you are using in PHP and check it's compatibility with you MSSQL version.
Maybe can be a good idea a fresh PHP install, with the latest stable release, if it is possible. Give a look at: http://www.php.net/manual/en/mssql.requirements.php
Good luck.
