I have come across quite a few post regarding the same subject question, however I am still unable to resolve it and so I ask. I am trying to connect to sql in my php script. My connection string is:

/* Specify the server and connection string attributes. */ $serverName = "xxx-PC\SQLExpress"; $connectionOptions = array("Database"=>"Salesforce"); $conn = sqlsrv_connect($serverName, $connectionOptions); if($conn === false) { die(print_r(sqlsrv_errors(), true)); } 

I have installed and included the following in my php.ini file located under the wamp folder: C:\wamp\bin\php\php5.4.16:

extension=c:/wamp/bin/php/php5.4.16/ext/php_sqlsrv_53_ts.dll 

My wampserver is running fine and so are the wampapache and wampsqld services. I am able to execute php.exe successfully. However I am unable to make the connection to SQL Server 2008 R2 where my database is located. Please help!

EDIT 1: The wamp server is running the wampmysql service while I am trying to connect to SQL Server 2008 R2. Could this be the reason? Should I be using MySQL instead of SQL? Any pointers?

EDIT 2: I do not see sqlsrv section at all when I run phpinfo() though I have added extension=php_sqlsrv_54_ts.dll in the php.ini file located in the bin folder of the wamp server.

When you install third-party extensions you need to make sure that all the compilation parameters match:

• PHP version
• Architecture (32/64 bits)
• Compiler (VC9, VC10, VC11...)
• Thread safety

Common glitches includes:

• Editing the wrong php.ini file (that's typical with bundles); the right path is shown in phpinfo().
• Forgetting to restart Apache.

• Not being able to see the startup errors; those should show up in Apache logs, but you can also use the command line to diagnose it, e.g.:

  php -d display_startup_errors=1 -d error_reporting=-1 -d display_errors -c "C:\Path\To\php.ini" -m 

If everything's right you should see sqlsrv in the command output and/or phpinfo() (depending on what SAPI you're configuring):

[PHP Modules]
bcmath
calendar
Core
[...]
SPL
sqlsrv
standard
[...]

This helped me get to my answer. There are two php.ini files located, in my case, for wamp. One is under the php folder and the other one is in the C:\wamp\bin\apache\Apachex.x.x\bin folder. When connecting to SQL through sqlsrv_connect function, we are referring to the php.ini file in the apache folder. Add the following (as per your version) to this file:

extension=c:/wamp/bin/php/php5.4.16/ext/php_sqlsrv_53_ts.dll 

If you are using Microsoft Drivers 3.1, 3.0, and 2.0. Please check your PHP version already install with IIS.

Use this script to check the php version:

<?php echo phpinfo(); ?> 

OR

If you have installed PHP Manager in IIS using web platform Installer you can check the version from it.

Then:
If you are using new PHP version (5.6) please download Drivers from here

For PHP version Lower than 5.6 - please download Drivers from here

• PHP Driver version 3.1 requires PHP 5.4.32, or PHP 5.5.16, or later.
• PHP Driver version 3.0 requires PHP 5.3.0 or later. If possible, use PHP 5.3.6, or later.
• PHP Driver version 2.0 driver works with PHP 5.2.4 or later, but not with PHP 5.4. If possible, use PHP 5.2.13, or later.

Then use the PHP Manager to add that downloaded drivers into php config file.You can do it as shown below (browse the files and press OK). Then Restart the IIS Server

If this method not work please change the php version and try to run your php script.

Tip:Change the php version to lower and try to understand what happened.then you can download relevant drivers.

First check that the extension is properly loaded in phpinfo(); (something like sqlsrv should appear). If not, the extension isn't properly loaded. You also need to restart apache after installing an extension.

i have same this because in httpd.conf in apache PHPIniDir D:/wamp/bin/php/php5.5.12 that was incorrect

Search for sqlsrv extension in pdo_sqlsrv.

Got it fixed. Even though I specified the folder that everything was stored, in my case C:\shared it turns out that PHP was just looking in c:\ for the lumina-online-dependencies folder.

I copied it to C:\ and it now works

I'm using MAMP and PHP 8.1 on Windows 10. I needed to download the SQL Server drivers from Microsoft (https://learn.microsoft.com/en-us/sql/connect/php/download-drivers-php-sql-server?view=sql-server-ver16), and then extract and copy the proper driver dll in this folder:

C:\MAMP\bin\php\php8.1.0\ext

(Side note: Laravel uses PDO.)

And then reference it:

In this file: C:\MAMP\conf\php8.1.0\php.ini

Add this line: extension=php_pdo_sqlsrv_81_ts_x64.dll

And in this file: C:\MAMP\bin\php\php8.1.0\php.ini

Add this line: extension=pdo_sqlsrv_81_ts_x64

And of course restart the services / Apache.

Then I could connect like this:

try { $conn = new PDO("sqlsrv:server=$servername,$port;Database=$database;ConnectionPooling=0", $username, $password, array( PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION ) ); $sql = "SELECT * FROM Table"; foreach ($conn->query($sql) as $row) { print_r($row); } } catch (PDOException $e) { echo ("Error connecting to SQL Server: " . $e->getMessage()); } 

Hope that helps someone else!
