The SQLSRV download comes 8 driver files, four of
which are for PDO support. If you are running non-thread-safe PHP
(PHP 5.3), use the php_sqlsrv_53_nts.dll file. (You should use a
non-thread-safe version if you are using IIS as your web server).
If you are running thread-safe PHP, use the php_sqlsrv_53_ts.dll
file. Similarly for PHP 5.4, use the php_sqlsrv_54_nts.dll or
php_sqlsrv_54_ts.dll depending on whether your PHP installation is
non-thread-safe or thread-safe.
The most recent version of the driver is available
for download here: » SQLSRV 4.0 download. If you need
support for PHP 5.2 and/or PHP compiled with VC6, use the 2.0
release of the driver: » SQLSRV 2.0 download.
