FreeBSD上PHP的MSSQL连接

Question

As an extension of my question: Remote connect to SQL Server Standard Edition from PHP/FreeBSD

I'm trying to get our FreeBSD/Apache/PHP server to be able to query our WinServer2003/SQL-Server-2000 box. Please note that this is not for a public system, only for a internal reporting function - so performance is not the key at this point. The initial question helped me prepare the MSSQL server for connection, and is now getting some kind of response from it. However I haven't got a successful connection to it.

I have tried PDO_dblib, mssql (FreeTDS) - haven't tried ODBC. I would prefer if I could get PDO to work, so that's what I'm aiming at here - and it's also the most succesfull of the two I tried.

My PHP script that utilizes PDO:dblib

<?php 

ini_set('display_errors', 1); 
ini_set('log_errors', 1); 
ini_set('error_log', dirname(__FILE__) . '/error_log.txt'); 
error_reporting(E_ALL);

$servername = '192.168.1.51';
$port = '1433';
$serverdsn = $servername.':'.$port;
$username = 'webserver';
$password = '123456';
$dbname = 'oneServer_staging';

$sqlstatement = 'SELECT * FROM ordersp';

try 
        {
            $pdo = new PDO ("dblib:host=".$serverdsn.";dbname=".$dbname,$username,$password);
        } 
        catch (PDOException $e)
        {
            echo "Failed to get DB handle: " . $e->getMessage() . "\n";
            exit;
        }
exit; 

The result of this PDO:dblib script when running it in browser:

Failed to get DB handle: SQLSTATE[28000] Login incorrect. (severity 9)

And ind the MSSQL server's application log I find this:

EDIT after comment about FreeTDS

My PHP script that utilizes mssql_connect() / FreeTDS

<?php 

ini_set('display_errors', 1); 
ini_set('log_errors', 1); 
ini_set('error_log', dirname(__FILE__) . '/error_log.txt'); 
error_reporting(E_ALL);

$username = 'webserver';
$password = '123456';
$dbname = 'oneServer_staging';

$sqlstatement = 'SELECT * FROM ordersp';

$link = mssql_connect('MYMSDN', $username, $password);

if (!$link) {
    die('Something went wrong while connecting to MSSQL');
}

The result of this mssql/FreeTDS script when running it in browser:

The file /tmp/freetds.log shows nothing when executing the script, however if i use # tsql -C command, it's updated.

Answer 1

Does the following lines of code work?

ini_set('display_errors', 1); 
ini_set('log_errors', 1); 
ini_set('error_log', dirname(__FILE__) . '/error_log.txt'); 
error_reporting(E_ALL);

$username = 'webserver';
$password = '123456';
$dbname = 'oneServer_staging';
$servername = '192.168.1.51';

if (!$link = mssql_connect($servername, $username, $password)) {
   exit('Error: Could not make a database connection using ' . $username . '@' . $servername);
}

if (!mssql_select_db($dbname, $link)) {
   exit('Error: Could not connect to database ' . $dbname);
}
?>

Answer 2

Do you need this line in your freetds.conf file? Are you sure both sides are using UTF-8?

client charset = UTF-8

Here's the code I use to connect PHP to MSSQL from Ubuntu machines to Windows SQL Server, I don't know if it will help you or not but this code is up and running successfully right now so I know it works in our environment...

PHP:

<?php
try{
   $con = new PDO("dblib:dbname=$dbname;host=$servername", $username, $password);
}catch(PDOException $e){
   echo 'Failed to connect to database: ' . $e->getMessage() . "\n";
   exit;
}
?>

/etc/odbc.ini

# Define a connection to the MSSQL server.
# The Description can be whatever we want it to be.
# The Driver value must match what we have defined in /etc/odbcinst.ini
# The Database name must be the name of the database this connection will connect to.
# The ServerName is the name we defined in /etc/freetds/freetds.conf
# The TDS_Version should match what we defined in /etc/freetds/freetds.conf
[mssqldb]
Description             = MSSQL Server
Driver                  = freetds
Database                = MyDB
ServerName              = mssqldb
TDS_Version             = 8.0

/etc/odbcinst.ini

# Define where to find the driver for the Free TDS connections.
[freetds]
