带有USBWebserver的php的SQL服务器

I have installed the lastest version of sql-server for php. I use a simple USBWebserver and I have pasted all the driver files to the map C:\php\ext (see image below). In the file php\php.ini, I have place this string behind:

extension=php_sqlsrv_56_ts.dll

Here can you see all the files in C:\php\ext for running the driver: Whit this I have no errors (but maybe he didn't throw it).

Now my problem is when I make my connection to the sql server database. I have the following error:

Fatal error: Call to undefined function sqlsrv_connect() in c:oot\add.php on line 2

This is my code where I've the exception:

$conn = sqlsrv_connect( array("Database"=>"Immo"), ".\\SQLEXPRESS");

Can anyone help me?
Thanks and sorry for my poor english.

The string that you must place in your php\php.ini file is this:

extension=php_sqlsrv_54_ts.dll

And for make a connection you must turn the two arguments from place.

$conn = sqlsrv_connect(".\\SQLEXPRESS", array("Database"=>"Immo"));

This has help me to make a connection to a SQL-server with php.
