I'm having issues retrieving the output parameters from a stored procedure. My work around for now was to just end the stored procedure with a select like the following: SELECT @out1 AS 'out1', @out2 as 'out2', @out3 as 'out3'; That works fine, but I don't understand why I wasn't able to get the output parameters. Take the procedure below for example (I simplified it for posting purposes). CREATE PROCEDURE [dbo].[test_procedure] @out1 int OUTPUT, @out2 int OUTPUT, @out3 int OUTPUT AS BEGIN SET NOCOUNT ON; ... business logic that sets those 3 variables ... SET NOCOUNT OFF; END The official examples I find do not use references while others do. Not sure what is correct in this case and there is confusion (definitely on my part) on which is correct. $sql = '{call dbo.test_procedure(?, ?, ?)}'; $out1 = 0; $out2 = 0; $out3 = 0; $stmt = sqlsrv_query($this->db->conn_id,$sql,array( array(&$out1, SQLSRV_PARAM_OUT), array(&$out2, SQLSRV_PARAM_OUT), array(&$out3, SQLSRV_PARAM_OUT), )); Those three variables will remain 0. I've tried without reference, specified SQLSRV_PHPTYPE_INT and SQLSRV_SQLTYPE_INT, to no avail. Any thoughts on what I am missing? I'm using the sqlsrv drivers version 3.0.1, SQL Server 2008 R2, and PHP 5.4.3.
