Executing Stored Procedure in MS SQL Server and displaying result in PHP

Hi Experts,

I am trying to execute a stored procedure in SQL SERVER and display the result in PHP.
Here is the Stored Procedure, which does return a value in SQL Server:

CREATE PROCEDURE [dbo].[eAdmissions_Exec_StuSeq]      
AS
BEGIN
      SET NOCOUNT ON;

   DECLARE @i INT;

   EXEC dbo.eAdmissions_GetNextSeq_Stu
   @pSequenceValue = @i OUTPUT;
   SELECT @i as SEQ;
   RETURN @i
END

What do I need to do in PHP to display the result? Is it something like this?

$query = "EXEC eAdmissions_Exec_StuSeq";

$rs = get_recordset ( $conn, $query );

while(odbc_fetch_row($rs)) {
        echo odbc_result($rs, 1);
}


What I am doing wrong?
