What is the best PDO driver to connect SQL server from php. So far I have found found two extension:
sybase DBLIB
Microsoft official driver for SQL server as specified here here. It works in php7. It works on linux. I have installed. It is working
I installed DBLIB at first place. But DBLIB is showing following error very randomly:
SQLSTATE[01002] Adaptive Server connection failed (severity 9)
It is not for config. Reason if I reload the page that error goes off and everything starts perfectly. It happens very randomly and rarely.
Using Microsoft official driver will help me in this case? Can you please suggest me what shall I do? Which will be better driver to connect sql server and also solves that randomly occurring problem?
DBLIB is becoming obsolete. We need to use PDO_SQLSRV in all place

I got a PHP project which uses Medoo for accessing a database on MS SQL Server 2012. I used to test my project on the same server, but since copy-pasting through remote desktop got kinda annoying and inefficient, I wanted to move on a local system, so I installed Xampp (with PHP 5.6.19 VC11). Since I still need to use the server database, I first encountered the problem that the PDO MSSQL extension is not available anymore, and my script failed to send a query to the database. So tried using the SQLSRV 3.0 extension instead (5.4 thread-safe - why isn't there a version 5.6? Is 5.4 supposed to be forward compatible?), which still sends me an uncaught exception with message 'could not find driver', thrown from the PDO constructor and forwarded through Medoo. I'm not sure if this fails on Medoo, the driver, or something else. Moving the database to phpMyAdmin is no option... Has anyone an idea how I can solve this?
All information you need are on this this web page https://msdn.microsoft.com/en-us/library/cc296170(v=sql.105).aspx.
As you can see you need version 3.2 for PHP 5.6 support. I found download link and information about adding SQLSRV extension to php.ini for you.
https://www.microsoft.com/en-us/download/details.aspx?id=20098
https://msdn.microsoft.com/en-us/library/cc296203(v=sql.105).aspx
Finally you have to install Microsoft ODBC Driver 11 for SQL Server.
In short, download SQLSRV 3.2, add PDO extension to php.ini (choose right version for your PHP), install Microsoft ODBC Driver 11 for SQL Server on your local enviroment.
I was trying to connect to a Microsoft SQL Database with PHP using the mssql set of functions that WERE in php. Since I am using php 5.5, these functions are deprecated I think, but I read that there is a solution, which is downloading the drivers windows is providing. I downloaded and installed them from the following link:
https://www.microsoft.com/en-us/download/details.aspx?id=20098
Now the only thing is unclear to me is how to use them. Do these drivers re-activate the mssql (which I am sure it is not the case since I tried the code using mssql_connect and it threw a php error saying that the function could not be found)?
Can anybody give me an example of a MSSQL connection with these drivers?
Thanks a lot for your time and help!
Cheers!
I am trying to get PHP with the SQL Server driver working under IIS. I had a similar situation 18 months ago with lesser versions of the php and the driver and Apache, and that code worked fine working on Windows Server 2003.
I am trying to set it up on my Windows 7 (Home Premium) Virtual Machine to work out how to do it, before attempting to get the same done on a Windows Server 2011.
Now I am coming to try the same code again and reset up my development environment. This time I am using PHP 5.5 and have installed the threadsafe version version of the driver php_pdo_sqlsrv_55_ts.dll obtained from the downloadable SQLSERVER31.exe file.
Doing all of this in 32 bit mode
As soon as I try and construct a new PDO I get the following error message
SQLSTATE[IMSSP]: This extension requires the ODBC Driver 11 for SQL
Server to communicate with SQL Server. Access the following URL to
download the ODBC Driver 11 for SQL Server for x86:
http://go.microsoft.com/fwlink/?LinkId=163712
So although that link isn't directly to the driver, I eventually find my way there and download it, only for it to fail to install. However, I think that might be because I already have the ODBC Driver 11 for SQL Server installed.
So according to my Data Sources (ODBC) application in the Administrative Tools Section there are two SQL Server ODBC drivers
SQL Server, verion 6.01.7602.17514 SQLSRV32.DLL Dated 21/11/2010
SQL Server Native Client 11, version 2011.110.5058.00 SQLNCLI11.DLL Dated 15/05/2014
So I really don't know how to go from here.
Can I remove a driver and re-install it. If so how?
Any other suggestions as to how to get this to work.
I discovered the answer to my problem. I hadn't installed the odbc driver - the drivers listed above are not the correct ones.
The reason the ODBC driver I downloaded failed to install wasn't because the driver was already installed - it was because I had downloaded the 32 bit version, and it HAS to be the 64 bit version.
As soon as I installed the 64 bit version, another entry appeared in the Data Sources Driver list, and my test program started to work
I am trying to access an SQL Server.
UPDATE: In response to Clive's comments below I have also tried reinstalling the native ODBC driver but no change.
I've checked over all the questions I can find on this and everything seems to be in order. My server details:
PHP 5.4 (Managed via Plesk)
SQL Server 2008 R2 SP2
Windows Server 2008 R2
The latest mssql drivers for PDO are in the EXT directory and referenced in php.ini:
extension=php_sqlsrv_54_nts.dll
extension=php_pdo_sqlsrv_54_nts.dll
PHPINFO() gives the following:
PDO Drivers: mysql, sqlite, sqlsrv
pdo_sqlsrv support: enabled
sqlsrv support: enabled
My connection string looks like this:
$DSN = "sqlsrv:Server=myDbServer,1433;database=my-dbname";
$PdoOptions = array(
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC
);
$sparklyGenericPdoObj = new PDO($DSN,'myUsername','myPasswurde', $PdoOptions);
But that just gives me the following error which links - in a roundabout way - to the drivers I already have installed (I've checked the version numbers):
PHP 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'
On this thread (reporting exactly the same error as me) is a solution which says that you can confirm the driver is installed by looking for the items I've mentioned above in PHPINFO: Not getting connected to Sql Server 2012!
Any help would be much appreciated!
Although it is a fairly old post, I've decided that it would be better to place my answer here instead of creating an other question...
after 3 weeks of research all over the Web and testing a lot of hypothesis around php installation, php code and drivers installation, I finally found the solution to this question.
THE PROBLEM:
I have an app that is installed on WIN SERVER 2012 SP2 and running under IIS.
The development of this app is made on a WIN 7 SP1 and running under 32-bit XAMPP 3.2.2. All of these are running PHP 5.6.
Everything is working fine on the server but I keep having this message when executed locally on XAMPP:
This extension requires the Microsoft ODBC Driver 11 for SQL Server to communicate with SQL Server
Even though I've installed this driver many times (with other php drivers found here, configure my php.ini to load php_sqlsrv_56_ts.dll and php_pdo_sqlsrv_56_ts.dll), it keeps returning me the same message...
The PDO command I've used to connect to distant MSSQL Server was:
$db = new PDO("sqlsrv:server=192.168.165.XXX;Database=testDB;", "userName", "passWord");
I have tried other drivers and it worked fairly well with ODBC driver;
$db = new PDO("odbc:Driver={SQL Server};Server=192.168.165.XXX;Database=testDB;", "userName", "passWord");
but I've found that there was some limitations with the later driver that I didn't experience with sqlsrv on the PROD server so I decided to push a little bit more my research to find a way to implement sqlsrv on my local machine...
THE INVESTIGATION:
Before connecting with PHP, I've tried to create System DSN (Data Source Name), with the ODBC Source Administrator (ODBCSA) application and test connection from there before trying to connect with my application.
Something pretty strange I have discovered with Win7, is that there are two different ODBCSA applications.
The 32-bit version of the Odbcad32.exe file is located in the %systemdrive%\Windows\SysWoW64 folder.
The 64-bit version of the Odbcad32.exe file is located in the %systemdrive%\Windows\System32 folder.
The 32-bit version of the ODBC Administrator tool displays 32-bit system DSNs, 32-bit user DSNs, and 64-bit user DSNs.
The 64-bit version of the ODBC Administrator tool displays 64-bit system DSNs, 32-bit user DSNs, and 64-bit user DSNs
Just to make sure what ODBCA your are using, check in Task manager under odbcad32.exe, if you see *32 on its right, that means its the 32-bit version.
At first, I executed the 64-bit ODBCSA, created DSN using the brand newly installed ODBC Driver 11, called ODBC_11_64 and test the connection using the ODBCSA. All worked fine. When I tested my code I received an other error message:
The specified DSN contains an architecture mismatch between the Driver and Application
Ok then, I tried to create an new DSN using the 32-bit ODBCSA. It was strange at first, when I've discovered that there was no version number aside some driver names and I received this error from the ODBCSA:
The setup routines for the ODBC Driver 11 for SQL Server could not be found. Please reinstall the driver.
and an other message:
Component not found in the registry
It was obvious that there was an installation problem and the later message point me in the right direction, the Registry...
Starting regedit as admin, I've found that all 64-bit ODBC drivers can be found here:
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI
All 32-bit ODBC drivers can be found here:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC\ODBCINST.INI
While trying to access the 64-bit key (\ODBC Driver 11 for SQL Server), I was able to display key values but when I tried to access the 32-bit key, I received this message:
Error Opening Key, ODBC Driver 11 for SQL Server Driver cannot be opened.
An error is preventing this key from being opened.
Details: Access is denied.
THE SOLUTION:
By right clicking on the 32-bit faulty key I was able to access permission interface. I was then able to add my username (I could also add a group) and granted full Control on the registry key.
I then came back to creating an new DSN using the 32-bit ODBCSA and ODBC Driver 11 for SQL Server, tested the connection with SUCCESS! :-)
I when back to my application and found that I was able to access the distant MSSQL SERVER using sqlsrv, on my local machine.
All along it was the driver installation package that was faulty! I should had install permissions to SYSTEM, users and administrators to the key has it did with the 64-bit registry key for this driver.
It was a pretty long story but I thought it was worth it, since a lot of persons tried to solve this complex problem, going in many different directions without success. Its also my contribution to all of you, who failed to find the solution but helped me in my investigation ;-)
i have fond some config in php.ini but was noted;
;extension=odbc
;extension=pdo_mysql
;extension=pdo_oci
;extension=pdo_odbc
remove “；” before, restart service, and it is worked!
In the end I solved this by installing the "Microsoft® SQL Server® 2012 SP1 Command Line Utilities" from here (SqlCmdLnUtils.msi):
http://www.microsoft.com/en-in/download/details.aspx?id=35580
No idea why this worked but there it is.
I have recently starting to learn PHP, and a few things I'm struggling now is the connection to a MSSQLS database. I learned in some well quoted websites that the most common (and best) way for using a SQL DB with PHP is using PDO.
So, this was what I have done so far:
1- Successfully installed the drivers:
extension=php_sqlsrv_55_ts.dll
extension=php_pdo_sqlsrv_55_ts.dll
(I have checked in phpinfo(), and my version of PHP is thread safe)
2- Drivers are recognized in the phpinfo()
3- I keep getting this error:
4- 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' in C:\xampp\htdocs\catala4\testdb.php:4 Stack trace: #0 C:\xampp\htdocs\catala4\testdb.php(4): PDO->__construct('sqlsrv:Server=H...', 'USER', 'PASSWORD') #1 {main} thrown in C:\xampp\htdocs\catala4\testdb.php on line 4
when executing this code:
<?php
include_once 'configs.php';
$mysqli = new PDO("sqlsrv:Server=HOST;Database=DATABASE", "USER", "PASSWORD");
I have no idea what is wrong, and i would like some help solving this issue, so my questions are:
What exactly is ODBC Driver? Is it the driver needed for the connecting with the SQLS ?
Considering i am using PDO to connect to a database, being PDO a middle interface to acess any DB, can i then say that any generic code used by this interface works with all the supported databases?
What is the error i am getting and what should i do / where should i find more information to solve the problem?
USING PHP v 5.5.9

Yes, it is . Please read up on ODBC

wrong ODBC is the middelware.
What is the error i am getting and what should i do / where should i find more information to solve the problem?
Problem:
Driver is not installed.
Solution:
Download and install ODBC driver.
To fix this same issue i downloaded from
http://www.microsoft.com/es-ar/download/details.aspx?id=35580
click on Download and select the package
sqlncli.msi
which is exactly what is missing.
Hope it helps, worked for me. =)
Xampp 1.8.3-3, PHP 5.5.9, same as you
You've just to install MS ODBC Driver 11 for SQL Server from this link
