I am getting a pdo exception "could not find driver" when trying to access MySql through PDO using hacklang/hhvm (compiled today). I tried installing php5-mysql but I'm not even sure that is helpful because I'm not sure of the relationship between php and hacklang especially in terms of extensions. What can I do to get PDO working on hacklang?
Update:
I found this list of supported extensions:
https://github.com/facebook/hhvm/wiki/Extensions
PDO and MySql are both on there but should I be looking for mysql_pdo? Or is there some configuring I need to do?
I solved it merely by rebuilding from scratch per the advice on peoples on the IRC channel. I honestly don't know what went wrong.

Connecting to MSSQL using Doctrine2 on Unix
Im currently developing a project which uses Doctrine2 with PHP on an Ubuntu Server (x64). It's required to fetch data from a MSSQL-Server which is running externally.
Problem
Doctrine2 doesn't support the pdo_dblib driver, neither there's a support for sqlsrv on unix-like machines (sqlsrv is windows only). Being that given, it seems like Doctrine simply doesn't have a built-in support for MSSQL-Servers on unix-machines.
Solutions
These are solutions I tried without success.
1. Write own wrapper for pdo_dblib and integrate in doctrine's DBAL
I couldn't figure out how to write my own driver, platform and schema for doctrines DBAL neither found anything usefull in its docs or per google.
Actual Question
Is there any kind of support for MSSQL-Servers with Doctrine 2 without using Symfony or other third-party code ?
Your original solution is not actually that hard to achieve. I've run into this issue trying to connect to SQL Server using ODBC, which is one option for linux hosts, and the only change that I needed was in this file.
If you update that function and use a valid ODBC connection string instead, it will work just fine. Of course the Doctrine folks didn't make it easy by making that function private, so you'll either have to resort to editing your library or copy/pasting the entire SQL Server driver code.
That said, SQL Server support with ODBC is somewhat poor. For example, I've run into an issue where exceptions are thrown if you use bound parameters inside a subquery. Even though it works just fine with Microsoft's official driver which itself is based on ODBC. Go figure. If possible, copy your data to a more Linux friendly database and work with it there.
My php installed with pdo_mysql, without mysqli/mysql. When I use phpMyAdmin, it showed
"The mysqli|mysql extension is missing".
I tried many times to install mysqli/mysql but failed, and I don't want to re-compile php. So I gave up and chose another mysql web tool Adminer which can use pdo_mysql.
Question : Is it possible that phpMyAdmin use pdo_mysql to access mysql db? I think it should be not hard ,since another tool can.
This information is not immediately available in the online documentation, but the FAQ has it:
phpMyAdmin can connect to your MySQL server using PHP’s classic MySQL extension as well as the improved MySQL extension (MySQLi)
The phrasing is more explicit in their Wiki:
[Requirements]
(...)
Either the mysql or mysqli extensions
(...)
So the answer is: not by default, but contributions are welcome :)
We have a CakePHP 1.3 application that we're in the process of upgrading to 2.2.3. One of the requirements of our app is to be able to query into an MSSQL database of a separate application to do some authentication and to pull user data out.
After two wasted days of researching and harassing our webhost to install the PHP / PDO / MSSQL lib (we already have PDO for MySQL, sqlite and sqlite 2) it's staring to seem pretty grim.
TL;DR: We need to find a way to do PDO MSSQL queries under Linux.
Begin Rant:
The thing that's driving me crazy is this: The CakePHP devs BROKE MSSQL compatibility for the sake of making all their DB wrappers with PDO. If you had a 1.3 app on a Linux server that was happily connecting to MSSQL databases and want to upgrade it to 2.2, you will no longer be able to connect to that database because apparently using PDO is more important than ensuring that you don't destroy existing functionality for your users.
CakePHP 2.x Docs do NOT warn users of this pitfall, all they say is that you need PDO.
There should be a notice that PDO/MSSQL does not work under Linux, or there should be an alterantive to the Sqlserver.php datasource that's provided with stock CakePHP so that people upgrading their apps have a chance of getting their applications functional again under 2.2x
I am really steamed about this right now because I wasted a week of time porting things over from 1.3 to 2.2 and now it looks like I either have to manually write the queries and ignore CakePHP's great database abstraction, or I need to convert all my work BACK to 1.3 and give up all the new improvements in the latest version of CakePHP.
The trick is :
sudo apt-get install php5-sybase
For some reason extension is not called mssql
sybase worked fine for me
What you need to do is install the ODBC drivers from Microsoft and set up the odbc connection strings. The process can be a bit tricky but it does work, and the driver is stable.
You can then use $dbh = new PDO("odbc:CONNECTIONNAME", $user, $password); to connect through PDO.
Once that is sorted, I think you can still use the MSSQL data source but modifying the connection string.
My company uses the sqlserv extension to connect to a MSSQL database. This extension was chosen over the mssql extension because it is actively being maintained by Microsoft and the mssql driver is no longer maintained at all. My colleague has always worked in a windows enviroment so he could just download the proper DLL file and voila, sqlserv is available. Since i am running on Mac OSX 10.8.1 i don't share this luxery.
So basically the question is: does anyone know of a sqlserv php extension in the form of a .so file?
You cannot run the SQLSRV extension on anything other than Windows as stated here:
http://php.net/manual/en/sqlsrv.installation.php
However, even if you could, I would strongly urge you to stay away from the SQLSRV extension as it is extremely buggy and underdeveloped. You would be much better off using PDO!
I spent days trying to work out which extension to use, and after much research and questions on stackoverflow, it was clear that PDO was the only realistic solution for connecting to an MSSQL database. Not to mention the additional functionality that you have!
Try and execute stored procedures, return multiple recordsets along with output parameters using the SQLSERV extension!! Just one of the many features that can be done in a few lines with PDO but cannot be done with SQLSERV.
Furthermore, PDO is faster!
So basically here's my problem. I'm looking for a solution to allow us to connect with SQL Express 2008, while still using MDB2 as our database abstraction layer. I need something like this, mainly because we still need to be able to use MySQL and Postgres (and ORMs seem to be not an option at this point in time).
Preferably, there would be a solution that works for both PHP5.2 and PHP5.3.
At first I went down the php_mysql extension road... it seems, though, as though that is not available in PHP 5.3.
php_pdo_mssql doesn't seem to be usable with MDB2, so that seems to be out.
Finally, there's the MS developed 'SQLSRV' extension, and while it seems as though there was work on a MDB2 'extension' for it at one point, it doesn't seem to have ever made it into the main branch.
Please... does anyone have any solutions for me?
For anyone else looking for information on this... so far, I have got SQL Express 2008 working with MDB2 running under PHP 5.2.
I have not yet tried connecting to a remote server: so far, I have only connected to SQL Express running on localhost.
I'm not sure if the PHP I am using shipped with the php_mssql.dll extension or not: either way, I disabled it. Instead, I used the php_dblib.dll that I downloaded from links on http://docs.moodle.org/en/Installing_MSSQL_for_PHP . This library is a build of FreeTDS (from freetds.org). I have not done any major testing with it yet, but I can connect to it, and I have been told by a colleague that they are having 'actual' success with it.
php_dblib.dll provides 'replacement' functions for the mssql_* functions that php_mssql.dll provided. Therefore, you need to disable the php_mssql.dll extension before enabling the php_dblib.dll one.
Other little things to note:
1) whereas most documentation on SQL Express and PHP state that you have to include the 'instance' name in the host section of the DB connection information, I found that this did not work for me: in fact, I had to explicitly remove the "\SQLEXPRESS".
2) while the Moodle link above provides PHP 5.3 builds of php_dblib.dll, unfortunately they are built with VC9. The install of PHP 5.3 I have was built with VC6 and so I am still working on building my own php_dblib.dll for PHP 5.3.
Anyway, I hope that this helps people who are having the same problem.
