Hi I have this SP to execute at php but I have no Idea how to do it

this is the way I execute it on MSSQL

[CODE=sql]DECLARE @TranID int
BEGIN TRANSACTION
EXEC sp_TransactionM odify @TranID output, 1, 100.00, 0, 100.00, 123, 456, “2008-08-20”
COMMIT
SELECT @TranID as TransactionID[/CODE]

How can I do to make it work at php??

Thank you so much!!!!
