Php PDO SQLSRV和PDO Dblib为Varbinary数据类型提供了不同的结果

上述代码在Linux（PDO、DBLIB）中的输出为：

上述代码在Windows（PDO、SQLSRV）中的输出为：

我需要在Windows源代码中做哪些更改才能获得与Linux系统相同的输出

$conn = new PDO("sqlsrv:server=$host;Database=$db",$user,$pass);
$query = "SELECT TOP 1 CAST(session AS VARBINARY(MAX)) as session FROM t_php_session WHERE php_session_id = '3l7kmpbno002e1vl5sncauhoq3' AND DATEADD(minute, 30, created) >= GETDATE() AND user_ip = '127000000001'";
$stmt = $conn->prepare($query);
$stmt->execute();
$result = $stmt->fetchColumn();
echo $result;
