I installed XAMPP on Windows Server 2008. Apache is running with PHP 7.0.13. I modified php.ini file for to enable ODBC driver, like this:
extension=php_pdo_odbc.dll
Even, I see ODBC in PDO drivers section when I use phpinfo(). But, I get an error when I use odbc_connect.
How fix this? Please, help me. Thanks.
PHP offers two kinds of support for ODBC (and most database drivers):
Through PDO
Standalone
You have enabled the PDO version (php_pdo_odbc.dll), but you're trying to use a non-PDO function. You've got two options:
Enable the standalone functionality via php_odbc.dll (note the slightly different name)
Use ODBC via the PDO interface
PDO is
a lightweight, consistent interface for accessing databases in PHP
and I generally prefer it to the database-specific interfaces, but either should work.

My default php.ini file lists both extensions (installed via brew), and I sometimes see different variations on Linux (AMZN vs Centos) with the _pdo_ bit. What is the difference?
Update: I was getting errors saying pg_connect not found and this seems to be part of the non-PDO version. To get this installed on Mac via brew, I needed to add support by running brew reinstall php56 --with-postgresql
PDO is short for PHP Data Objects and is an abstraction that can be mapped on to a lot of different databases. This means you can move between things like MySQL, PGSQL and SQLite very easily. The PDO module enables the functions you see here for PGSQL.
The non-PDO module is specific to Postgres and will enable this set of non-standardized functions that will only work with Postgres databases.
The PDO extension can connect to different database management systems with the same syntax, as long as there's a driver for the system you want to use. The PostgreSQL extension can only connecto to PostgreSQL.
What you see is the PostgreSQL extension and the PDO driver for PostgreSQL.
I have installed Apache2.2 and then installed PHP5.4.8. I cannot get my new .php file to load in a browser because it keeps giving me the error Fatal error: Call to undefined function mysql_connect(). When I load the test.php file which has only this in it:
<?php phpinfo(); ?> it returns a page that shows information about PHP but where it would show the MySQL modules it only shows mysqlnd. What is that? Also, I have gone through the php.ini file and uncommented the proper lines for MySQL integration as well as having edited the Apache2.2 httpd file. Does anyone have any answers as to why MySQL isn't working? Thanks in advance.
Also, Ive tried many of the solutions from this website as well as many google searches. I can't seem to figure it out. :-(
1) Have a look on choosing MySQL API. It is recommended to use mysqli extension.
2) According to Other changes to extensions, the MySQL extensions mysql, mysqli and PDO_mysql use mysqlnd as the default library now.
A quote from MySQL Native Driver - mysqlnd site:
Although MySQL Native Driver is written as a PHP extension, it is important to note that it does not provide a new API to the PHP programmer. The programmer APIs for MySQL database connectivity are provided by the MySQL extension, mysqli and PDO MYSQL. These extensions can now use the services of MySQL Native Driver to communicate with the MySQL Server. Therefore, you should not think of MySQL Native Driver as an API.
That means, the mysqlnd extension does not export any function you can use in your scripts, but acts as a bridge between your code and one of mysql, mysqli, pdo_mysql extensions.
You mentioned, that phpinfo() shows only mysqlnd. The fact you don't see section titled MySQL there means that mysql extension is not enabled (commented out) in php.ini (Windows) or your php is not compiled with mysql support (Linux). More details about installing MySQL extension are here.
What is your OS?
To have a successfull MySQL connection you should:
Install the MySQL Server
Configure the PHP to use the proper mysql socket: (in php.ini search for mysql.default_socket - point it to the mysql server).
Reboot the web server - Apache
I am currently trying to connect to my localdb on MSSQL 2012 Express.
I have downloaded and installed the official microsoft driver from http://www.microsoft.com/en-us/download/details.aspx?id=20098
I get some kind of SQLSRV section in my phpinfo(). But when I try to create a new PDO object it says it does not have the driver. Which I could understand since it is not mentioned on the phpinfo() PDO section, but it has its own section + the get_loaded_extensions also shows sqlsrv. I suppose thats from the official MS Driver ? I am using the php_sqlsrv_53_nts.dll
With my Zend Server CE 5.6 with PHP 5.3.9
Now as far as I understood I downloaded the wrong driver and should try the one that is brought by the PECL manager? There is only the sourcecode available and obviously I am on a windows machine so I can forget about everything that I need to compile myself - I am actually getting the suffix errors when using the powershell and my pecl / pear installation.
Has anybody solve that problem ? Any help much appreciated
All the best,
Richard
The PDO Extension is not the same as the native driver Microsoft is offering. For PDO you must enable
extension=php_pdo_mssql.dll
in your php.ini.
Normally this file (php_pdo_mssql.dll) should be in your PHP extension-directory (C:...\php\ext). If it's not there you can download PHP from http://windows.php.net/download/ and just take the extension from a package there (take one that correspond with your PHP version of course).
//edit: just read you latest comment. This extension is available for a very long time now and can be considered working. If you are not allowed to use it you must rewrite your code to use the functions the native driver offers for PHP.
Another possibility is to use the odbc drivers which are by default included in the php extensions, you still might have to uncomment them in your php.ini though.
extension=php_pdo_odbc.dll
Don't forget to restart your server afterwards ;-)
And then use it like this:
$db = new PDO('odbc:Driver={SQL Server};Server=192.168.x.x;Database=DatabaseName; Uid=User;Pwd=Password');
$stmt = $db->query("SELECT the_usual FROM aTable WHERE all='well'");
Alright. I suppose its just one of these days.
I got the wrong extension loaded from the supplied ones by MS. I needed to use php_pdo_sqlsrv_53_nts
rather than
php_sqlsrv_53_nts
Thanks for all the help
In php, to connect to MSSQL server , what is diffrence between odb_connect() and mssql_connect()???
odbc_connect is a generic database connection (you can specify the driver), while mssql_connect is MSSQL specific
Also the manual says that complex queries may fail with odbc drivers.
odbc_connect() requires you have the PHP ODBC extension loaded and UNIXodbc installed and configured on the web server, whereas mssql_connect() only requires that you have the MSSQL extension.
If your looking to connect to a SQL Server via PHP, might I recommend that you use Microsoft's SQLSRV PHP driver. It's much better than the native php_mssql extension and gives you a lot more functionality. Make sure you also install SQL Server native client, or it won't work.
I've inherited some code that uses the sqlsrv_connect method to instantiate a connection to a SQL Server database. My personal development machine is an OS X box that I'm running apache an PHP on. I have an instance of SQL Server running in a virtual machine.
When I attempt to connect to the database, I get the following error.
Fatal error: Call to undefined function sqlsrv_connect() in ...
It appears that sqlsrv_connect is not part of standard PHP, and is part of a driver that ships with SQL Server 2005. (please correct me if I'm wrong here)
Is there a way to use this function on Non-Windows platforms? I realize I could install/build an Apache/PHP instance on my Windows machine, but if there's a way to get this function working on OS X (or other *nixes) I'd prefer it.
Is not possible. The SQL Native Driver for PHP is Windows only product:
The SQL Server Driver for PHP relies
on the Microsoft SQL Server 2005 ODBC
Driver to handle the low-level
communication with SQL Server. As a
result, the SQL Server Driver for PHP
is only supported on Windows.
You can look here for a tutorial on how to install the extension. (Via Google)
I'm not too famillar with the extension, but that source should be able to help you out.
(Updated Link to Better Source, still via Google)
The SQL Server Driver for PHP (from MS) is available only on Windows. Unless you want some specific features offered by this driver/ API, you can use the PHP ODBC module along with UnixODBC/ iODBC driver, or FreeTDS (ODBC or db-lib)
