Call SQL Server stored procedure with output parameter from PHP - php

Question

I am trying to execute a sql server stored procedure from php. Stored procedure returns a output value. I want that value in php to display in webpage.
Everything works fine except the output value returns 0 in php.. but the row is getting inserted perfectly. the output value shows as 0. annoyed where I have made the mistake. Below is my php code
require('db.php');
$billno = "REF0001";
$retsno = 0.0;
$sp_name = "{call testinsert( ?, ? )}";
$params = array(
array($billno, SQLSRV_PARAM_IN),
array($retsno, SQLSRV_PARAM_OUT)
);
/* Execute the query. */
$stmt3 = sqlsrv_query( $conn, $sp_name, $params);
if( $stmt3 === false )
{
echo "Error in executing statement 3.\n";
die( print_r( sqlsrv_errors(), true));
}
echo "Inserted Retuern Sno for ".$billno." is ". $retsno. ".";
and my stored procedure is
create procedure testinsert(#bill_no VARCHAR(20),#RetSno INT OUTPUT)
as
begin
insert into testable values(#bill_no,GETDATE())
set #RetSno = ##IDENTITY
return
end

Answer 1

Maybe you missed scrollable. https://msdn.microsoft.com/en-us/library/hh487160(v=sql.105).aspx
$stmt3 = sqlsrv_query( $conn, $sp_name, $params, array( "Scrollable" => 'static'));

Answer 2

Before you use your echo, add the following line to read the next line:
sqlsrv_fetch($stmt3);
Then you can select the first field of the response, which should be your parameter, with sqlsrv_get_field():
$id = sqlsrv_get_field(0);

I had the same case, and solved it using:
sqlsrv_next_result($stmt);
at the end of the instruction. Here I put part of my code in case it helps you.
$totalPaginas = 0;
$result = array();
$query = "EXEC DBO.SPS_EJECUTAR_CONSULTA #ReporteID = ?, #FilasPorPagina = ?, #NroPagina = ?, #TotalPaginas = ?";
$params = array(
array(&$reporteid, SQLSRV_PARAM_IN),
array(&$filasPorPagina, SQLSRV_PARAM_IN),
array(&$nroPagina, SQLSRV_PARAM_IN),
array(&$totalPaginas, SQLSRV_PARAM_OUT)
);
$stmt = sqlsrv_prepare($this->db, $query, $params);
if( !$stmt ) {
// show errors
}
$result = sqlsrv_execute($stmt);
if( !$result ) {
// show errors
}
$data = array();
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
$data[] = $row;
}
sqlsrv_next_result($stmt);
var_dum($data);
echo('Total Paginas: '.$totalPaginas);
