PHP通过SQL Server存储过程调用获取空输出

Question

I am trying to call a stored procedure on MS SQL Server, but i get an empty result. The stored procedure takes the user id as input parameter, and outputs the name, address, city, state and zip code of the user.

Here is the execution query of Stored Procedure on SQL Server Management Studio:

USE [MYDB]
GO
DECLARE @return_value int,
        @Name char(60),
        @Address char(60),
        @City char(30),
        @State char(3),
        @Zip char(10)

EXEC    @return_value = [dbo].[spAddressByUserID]
        @UserID = N'AB1234',
        @Name = @Name OUTPUT,
        @Address = @Addr1 OUTPUT,
        @City = @City OUTPUT,
        @State = @State OUTPUT,
        @Zip = @Zip OUTPUT

SELECT  @Name as N'@Name',
        @Address as N'@Address',
        @City as N'@City',
        @State as N'@State',
        @Zip as N'@Zip'

SELECT  'Return Value' = @return_value
GO

So far, i have tried the following code:

<?php
$conn = sqlsrv_connect( $host, $connectionInfo);
$user_id = 'AB1234';
$myparams['UserID'] = $user_id;

$procedure_params = array(
    array(&$myparams['UserID'], SQLSRV_PARAM_IN),
    array(&$myparams['Name'], SQLSRV_PARAM_IN),
    array(&$myparams['Address'], SQLSRV_PARAM_IN),
    array(&$myparams['City'], SQLSRV_PARAM_IN),
    array(&$myparams['State'], SQLSRV_PARAM_IN),
    array(&$myparams['Zip'], SQLSRV_PARAM_IN)
);

$sql = "EXEC spAddressByUserID @UserID = ?, @Name = '', @Address = '', @City = '', @State = '', @Zip = ''";

$stmt = sqlsrv_prepare($conn, $sql, $procedure_params);

if( !$stmt ) {
    die( print_r( sqlsrv_errors(), true));
}

if(sqlsrv_execute($stmt)){
  while($res = sqlsrv_next_result($stmt)){
    print_r($res); // Gives Empty Output
  }
}
else{
  die( print_r( sqlsrv_errors(), true));
}

I think all my syntax is correct. But i get empty output. Not sure what i am doing wrong.

EDIT:

I have modified the array parameters of query like this, with no success:

$procedure_params = array(
    array(&$myparams['UserID'], SQLSRV_PARAM_IN, 'SQLSRV_PHPTYPE_STRING'),
    array(&$myparams['Name'], SQLSRV_PARAM_OUT, 'SQLSRV_PHPTYPE_STRING'),
    array(&$myparams['Address'], SQLSRV_PARAM_OUT, 'SQLSRV_PHPTYPE_STRING'),
    array(&$myparams['City'], SQLSRV_PARAM_OUT, 'SQLSRV_PHPTYPE_STRING'),
    array(&$myparams['State'], SQLSRV_PARAM_OUT, 'SQLSRV_PHPTYPE_STRING'),
    array(&$myparams['Zip'], SQLSRV_PARAM_OUT, 'SQLSRV_PHPTYPE_STRING')
);

Are you able to run the proc in SQL Management studio successfully? It also looks like you are missing some placeholders in your SQL in PHP. Only one ? in the query. Perhaps this is better?

$sql = "EXEC spAddressByUserID @UserID = ?, @Name = '?', @Address = '?', @City = '?', @State = '?', @Zip = '?'";

I'm not very familiar with stored procs of this kind, but with parameterized placeholders in prepared statements, you need to specify all the placeholders, in the correct order. From what you posted, it seems to me that you are not adding the placeholders in all the places it needs to go, and perhaps that is why you are not getting the output back?
