PHP - 调用未定义的函数mysqli_stmt_next_result

Question

我正在尝试使用以下代码从MySql存储过程中检索多个数据集，我收到错误

“调用未定义的函数mysqli_stmt_next_result”

我正在使用PHP版本5.6.2 使用MAMP（http://www.mamp.info/en/）

所有其他代码都有效，直到我尝试将第二个数据集添加到结果中。

感谢任何帮助，谢谢！

    $mysql_host = "localhost";
    $mysql_database = "dbname";
    $mysql_user = "username";
    $mysql_password = "password";

    $link = mysqli_connect($mysql_host, $mysql_user, $mysql_password ,$mysql_database);

    if (mysqli_connect_errno()) {
        printf("Connect failed: %s\n", mysqli_connect_error());
        exit();
    }

    $query = "CALL SprocName()";

    if ($stmt = mysqli_prepare($link, $query)) {

        mysqli_execute($stmt);
        mysqli_stmt_bind_result($stmt, $ID);

        $rtn = array();

        while (mysqli_stmt_fetch($stmt)) {  

            $resultrow = (object) [
                'ID' => $ID
            ];

            array_push($rtn, $resultrow);
        }


        mysqli_stmt_next_result($stmt);

        mysqli_stmt_bind_result($stmt, $ID);

        $rtn2 = array();

        while (mysqli_stmt_fetch($stmt)) {
            $resultRow = (object) [
                'ID' => $ID
            ];

            array_push($rtn2, $resultRow);
        }

        echo json_encode(array('Result1' => $rtn, 'Result2' => $rtn2));

        mysqli_stmt_close($stmt);

    } else {
        echo "Failed";
    }

    mysqli_close($link);
