PHP.ini - MS SQL SVR DLL not loading

I have installed PHP and MS SQL server 2014. When I test my php connection to Ms sql database, I get this error: Fatal error: Call to undefined function sqlsrv_connect() This is happening because Ms SQL DLL is not registering even though its installed. Below is the phpinfo() message: cscript /nologo [login to view URL] "--enable-snapshot-build" "--disable-isapi" "--enable-debug-pack" "--without-mssql" "--without-pdo-mssql" "--without-pi3web" "--with-pdo-oci=c:\php-sdk\oracle\x64\instantclient_12_1\sdk,shared" "--with-oci8-12c=c:\php-sdk\oracle\x64\instantclient_12_1\sdk,shared" "--enable-object-out-dir=../obj/" "--enable-com-dotnet=shared" "--with-mcrypt=static" "--without-analyzer" "--with-pgo"
