Q:

SQL Server Stored Procedure Output Params in PHP

I need help running a stored procedure from SQL Server in PHP.  PHP is running on a Unix/Linux server.  We cannot get OUTPUT variables to return in PHP.  The following is the PHP code:
$conn = mssql_connect('server', 'user', 'pass');
    mssql_select_db('db', $conn);

    $procedure = mssql_init('usp_StoredProc', $conn);

    $tmpVar1 = 'value';
    $tmpVar2 = 'value2';

    $outVar1 = '';
    $outVar2 = '';

    mssql_bind($procedure, "@var1", $tmpVar1, SQLVARCHAR, false, false);
    mssql_bind($procedure, "@var2", $tmpVar2, SQLVARCHAR, false, false);

    mssql_bind($procedure, "@outVar1", $outVar1, SQLVARCHAR, true);
    mssql_bind($procedure, "@outVar2", $outVar2, SQLVARCHAR, true);

    mssql_execute($procedure,$conn);

    print($outVar1);
    print($outVar2);

The stored procedure looks like so :
    SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER proc [dbo].[usp_StoredProc]
(
    @var1 as varchar(36), 
    @var2 as varchar(10), 
    @outVar1 varchar(36) OUTPUT, 
    @outVar2 varchar(36) OUTPUT 
)
as
  select distinct 
    @outVar1 = row1, 
    @outVar2 = row2
  from table1
  where column1 = @var1
    and column2 = @var2

Can anyone tell me why $outVar1 and $outVar2 are not being populated?  Thanks a lot for any help!

A:

According to this page on PHP bugs, you have to (emphasis mine):

call mssql_next_result() for each
  result set returned by the SP. This
  way you can handle multiple results.
When mssql_next_result() returns false
  you will have access to output
  parameters and return value.
