I believe it's time to revisit this answer a bit better. Since you've been pretty clear with your setup. The short answer is placed as steps below
Please delete the redundant files below:
PHP Drivers License Terms.rtf, php_pdo_sqlsrv_54_nts.dll, php_pdo_sqlsrv_54_ts.dll, php_pdo_sqlsrv_55_nts.dll, php_pdo_sqlsrv_55_ts.dll, php_pdo_sqlsrv_56_nts.dll, php_sqlsrv_54_nts.dll, php_sqlsrv_54_ts.dll, php_sqlsrv_55_nts.dll, php_sqlsrv_55_ts.dll, php_sqlsrv_56_nts.dll, release.txt, SQLSRV_Readme.htm, SQLSRV_ThirdPartyNotices.rtf,
Place these lines in your php.ini at your "xampp installation path"\php\php.ini extension=php_sqlsrv_56_ts.dll extension=php_pdo_sqlsrv_56_ts.dll
Restart your XAMPP server and place a '<'?php phpinfo(); ?'>' in an index.php file at \htdocs\'folder'
Navigate to it using http://localhost/'folder where phpinfofile is placed'/index.php
If you see something like this image below. It's done, Congratulations
