Question

I went through several questions and recommendation to resolve the above issue, but No luck at all.

I have the following settings:

Windows Server

Answer 1

I have struggled through the process and this is what has finally worked. I am using php 5.4.16 and Apache 2.4.4 with Sql Express 2008 R2.

1. Download Microsoft Drivers for PHP for SQL Server from Microsoft download site

2. Extact the files to a local folder

3. Copy php_sqlsrv_54_ts.dll and php_pdo_sqlsrv_54_ts.dll to the Ext folder (C:\wamp\bin\php\php5.4.16\ext). You can confirm the folder by checking the value of extension_dir in php.ini file stored under Apache (C:\wamp\bin\apache\Apache2.4.4\bin).
4. Add extension for the two drivers by adding these lines: extension=php_sqlsrv_54_ts.dll extension=php_pdo_sqlsrv_54_ts.dll and comment out the existing lines below if not commented: ;extension=php_pdo_mssql.dll ;extension=php_mssql.dll
5. Start all Wamp services

Answer 2

What worked for me on windows 10 64bit and php 5.6. is the 3.2 version of the driver downloaded from here:Microsoft SQL Server driver for PHP

Answer 3

Load the PHP drivers in php.ini file and restart the server.

extension=php_sqlsrv_53_ts.dll
extension=php_pdo_sqlsrv_53_ts.dll
