Description:
------------
binding input parameters is not really working.

This mechanism was working well in 4-th family of php.

Reproduce code:
---------------
php code here:

mssql_bind($Proc,'@Param1',$Param1,SQLVARCHAR,false,false,30); mssql_execute($Proc,FALSE) ||
  print(mssql_get_last_message());

MSSQL code here:

CREATE PROCEDURE [dbo].[test]
(
	@Param1              VARCHAR(30)
)

AS
RETURN 0
GO


Expected result:
----------------
successfull execution

Actual result:
--------------
Procedure 'test' expects parameter '@Param1', which was not supplied.
