php中怎样遍历sqlserver数据？

<code>$serverName = "192.168.135.211";
$connectionInfo = array( 
"Database"=>"AGGCRMTEST", "UID"=>"sa", "PWD"=>"123213");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false )
{
    echo "Could not connect.\n";
    die( print_r( sqlsrv_errors(), true));
}
$tsql = "exec [GetListByName] 'o'";
$stmt = sqlsrv_query( $conn, $tsql);
if( $stmt === false )
{
    echo "Statement 1 could not be executed.</br>";
    die( print_r( sqlsrv_errors(), true));
}else{
   $qty = sqlsrv_fetch_array( $stmt);
   sqlsrv_free_stmt( $stmt);
}</code>

<code>$serverName = "192.168.135.211";
$connectionInfo = array( 
"Database"=>"AGGCRMTEST", "UID"=>"sa", "PWD"=>"123213");
$conn = sqlsrv_connect( $serverName, $connectionInfo);

    die( print_r( sqlsrv_errors(), true));
}else{
   $qty = sqlsrv_fetch_array( $stmt);
   sqlsrv_free_stmt( $stmt);
}</code>

<code>php</code><code>$result = array();
while($qty = sqlsrv_fetch_array( $stmt)){
    $result[] = $qty;
}
sqlsrv_free_stmt( $stmt);
