I am trying to use PDO to connect to a SQL Server database. I have been struggling with it for a little bit now I get this Fatal error on my page where I am trying to connect to SQL Server
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[IMSSP]: This extension requires the Microsoft SQL Server 2012 Native Client ODBC Driver to communicate with SQL Server. Access the following URL to download the Microsoft SQL Server 2012 Native Client ODBC driver for x86: http://go.microsoft.com/fwlink/?LinkId=163712'
I have downloaded the drives from http://www.microsoft.com/en-us/download/details.aspx?id=20098 (SQLSRV30.EXE) I have placed those drivers in the ext directory where php is installed on the Server 2008 R2 server.
I also have added these 2 lines at the end of the extension list in the php.ini file
extension=php_pdo_sqlsrv_53_nts.dll
extension=php_sqlsrv_53_nts.dll
I am using PH PVersion 5.3.19 Server API CGI/FastCGI Thread Safety disabled
I do see pdo_sqlsrv but I don't see a Client API Version.
What else do I need to do to be able to use PDO to connect to the remote server that has SQL databses? Do I need to install anything on the remote servers?
this is a screenshot of my php my admin section
This is my connection class
<?php
class connection {
private $connString;
private $userName;
private $passCode;
private $server;
private $pdo;
private $errorMessage;
protected $lastQueryTime;
protected $lastQuery;
private $pdo_opt = array (
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"
);
function __construct($dbName = DATABASE_NAME, $serverName = DATABASE_HOST){
//sets credentials
$this->setConnectionCredentials($dbName, $serverName);
//start the connect
$this->startConnection();
}
function startConnection(){
$this->pdo = new PDO($this->connString, $this->userName, $this->passCode, $this->pdo_opt);
if( ! $this->pdo){
$this->errorMessage = 'Failed to connect to database. Please try to refresh this page in 1 minute. ';
$this->errorMessage .= 'However, if you continue to see this message please contact your system administrator.';
echo $this->getError();
}
}
//this will close the PDO connection
public function endConnection(){
$this->pdo = null;
}
//return a dataset with the results
public function getDataSet($query, $data = NULL)
{
$start = microtime(true);
$cmd = $this->pdo->prepare( $query );
$cmd->execute($data);
$ret = $cmd->fetchAll();
//$cmd->closeCursor();
$this->lastQueryTime = microtime(true) - $start;
$this->lastQuery = $query;
return $ret;
}
public function processQuery($query, $data = NULL)
{
$start = microtime(true);
//$this->pdo->beginTransaction();
$cmd = $this->pdo->prepare( $query );
$ret = $cmd->execute($data);
//$this->pdo->commit();
//$cmd->closeCursor();
$this->lastQueryTime = microtime(true) - $start;
$this->lastQuery = $query;
return $ret;
}
//return last insert id
public function lastInsertId($name = NULL) {
if(!$this->pdo) {
return false;
}
return $this->pdo->lastInsertId($name);
}
public function getOneResult($query, $data = NULL){
$cmd = $this->pdo->prepare( $query );
$cmd->execute($data);
return $cmd->fetchColumn();
}
public function getError(){
if($this->errorMessage != '')
return $this->errorMessage;
else
return true; //no errors found
}
//this where you need to set new server credentials with a new case statment
function setConnectionCredentials($dbName, $serv){
switch($serv){
//MS SQL server
case 'SQLSERVER':
$this->connString = 'sqlsrv:server='.$serv.';database='.$dbName;
$this->userName = 'username';
$this->passCode = 'password';
break;
//the defaults are predefined in the APP_configuration file - DO NOT CHANGE THE DEFAULT
default:
$this->connString = 'mysql:host='.DATABASE_HOST.';dbname='.DATABASE_NAME.';charset=utf8';
$this->userName = DATABASE_USERNAME;
$this->passCode = DATABASE_PASSWORD;
break;
}
}
public function lastQueryTime() {
if(!$this->lastQueryTime) {
throw new Exception('no query has been executed yet');
}
return $this->lastQueryTime;
}
public function lastQuery() {
if(!$this->lastQuery) {
throw new Exception('no query has been executed yet');
}
return $this->lastQuery;
}
}
?>
This is how I use my class to pull a dataset
<?php
include('connection.php');
$sql_db = new connection('databaseName','SQLSERVER');
$call_details = $sql_db->getDataSet('SELECT
LocalUserId AS loginName,
RemoteNumberCallId AS PhoneNumber,
SUM(CallDurationSeconds + HoldDurationSeconds + LineDurationSeconds) AS totalTalk
FROM dbo.CallDetail WHERE LocalUserId = \'blah\' AND RemoteNumberCallId = \'123456789\'
GROUP BY LocalUserId, RemoteNumberCallId');
$call_details->endConnection();
?>
I have even tried this code so I won't use my class and I still get the same error
$ss = new PDO("sqlsrv:server=SQLSERVER; Database=databaseName", "userName", "Password");
回答1:
I have replaced the
extension=php_sqlsrv_53_nts.dll extension=php_pdo_sqlsrv_53_nts.dll
With
extension=php_pdo_sqlsrv_53_nts_vc9.dll extension=php_sqlsrv_53_nts_vc9.dll
Insted on using SQLSRV30.EXE I used the SQLSRV20.EXE This worked.
@FreshPrinceOfSo Thanks for your help :)
Thanks :)

My personal installation for Windows Server 2008 R2 and configuration with PHP/SQL Server.
- Download the latest stable .zip release of VC9 x86 Non Thread Safe from PHP Downloads
- Extract into your PHP directory
- Download Microsoft Drivers 3.0 for PHP for SQL Server
- Extract into your PHP directory
\ext Write the following extensions to
php.ini[PHP_SQLSRV_54_NTS]extension=php_sqlsrv_54_nts.dll[PHP_PDO_SQLSRV_54_NTS]extension=php_pdo_sqlsrv_54_nts.dll
