note 110565 added to function.sqlsrv-query

Question Im using php 5.4 with sqlsrv extension and I'm trying to call this sample stored procedure (NorthWind database): create PROCEDURE [dbo].[GetCategories] @CategoryID int = null AS SELECT * from dbo.Categories where CategoryID= IsNull(@CategoryID,CategoryID) And I'm using this sqlsrv_query syntax: $sql = "{ call dbo.GetCategories (?)}"; $catID=2; $params = array($catID); $stmt = sqlsrv_query( $conn, $sql,$params); I want to specify parameter name and value in $params, just like this: $sql = "dbo.GetCategories"; $catID=2; $params = array("@CategoryID"=>$catID); $stmt = sqlsrv_query( $conn, $sql,$params); It return this error: String keys are not allowed in parameters arrays. How can i solve this problem?
