SQLSRV PDO could not be found

问题:

I'm trying to configure php_pdo_sqlsrv_55_ts.dll on Windows 7 x64, with on board XAMPP x86.

I've correctly installed the SQL Native Client 2012 and the Microsoft Visual C++ Redistributable (x64) package (I don't know if the last one is needed or not).

I've copied to C:\xampp\php\ext\ both the php_pdo_sqlsrv_55_ts.dll and the php_sqlsrv_55_ts.dll libraries downloaded from the unofficial release found here.

Then I've edited the php.ini adding the two libraries and restarted the Apache web server but in the phpinfo() page there are not traces of the sqlsrv driver.

The Apache error log says:

[21-Jan-2014 10:56:56 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library 'C:\xampp\php\ext\php_pdo_sqlsrv_55_ts.dll' - Could not find the specified module.

 in Unknown on line 0

What am I doing wrong? If I try to open the specified paths I can correctly find the 2 dll.

You have installed this:

• Microsoft Visual C++ Redistributable (x64)

... but you need the x86 version since that's the architecture of your extension.
