所需表的说明

研究组计划有一个输出处理程序。有必要将接收到的数据构造成与上述类似的表格。请写一部分渲染代码，然后我想我应该清楚。使用的处理程序：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html">

<title>Succesful</title>
</head>
<body>
<?php
require 'connect.php';
mysqli_set_charset($db_connect, 'utf8');
$group_number = $_REQUEST['group_number'];
$task_family = $_REQUEST['task_family'];
$week_day = $_REQUEST['week_day'];
$week_period = $_REQUEST['week_period'];
$task_lecture = $_REQUEST['task_lecture'];
$task_index = $_REQUEST['task_index'];
$sql_select = "SELECT COUNT(*) FROM `pisos` WHERE group_number LIKE '%$group_number%' AND (task_family LIKE '%$task_family%' OR task_family2 LIKE '%$task_family%') AND week_period LIKE '%$week_period%' AND week_day LIKE '%$week_day%' AND task_lecture LIKE '%$task_lecture%' AND task_index LIKE '%$task_index%'";
$result = mysqli_query($db_connect, $sql_select);
$result_sum=$result;
$iter=0;
do
{
$sql_select = "SELECT * FROM `pisos` WHERE group_number LIKE '%$group_number%' AND (task_family LIKE '%$task_family%' OR task_family2 LIKE '%$task_family%') AND (week_period LIKE '%$week_period%' or week_period LIKE '0') AND week_day LIKE '%$week_day%' AND task_lecture LIKE '%$task_lecture%' AND task_index LIKE '%$task_index%'";
$result = mysqli_query($db_connect, $sql_select);
while ($row = mysqli_fetch_array($result)) { print_r("<p>Номер группы: ".$row['group_number']."</p><p>ПАРА №: ".$row['task_index']." Чётность: ".$row['week_period']."</p><p>Начало: ".$row['task_start']." Конец: ".$row['task_finish']."</p><p>Дисциплина: ".$row['task_name']." ".$row['task_type']."</p><p>Аудитория: ".$row['task_lecture']."</p><p>Преподаватель: ".$row['task_family'].$row['task_family2']."</p><p>___________________</p>");
}
$iter++;
}
while ($iter<$result_sum);
$iter=0;
?>

我正在尝试使用此脚本连接到数据库

<?php 
$server = 'localhost';
$user = 'admin';
$password = 'admin';
$dblink = mysqli_connect($server, $user, $password, 'db');
if($dblink)
echo 'Соединение установлено.';
else
die('Ошибка подключения к серверу баз данных.');
if($dblink)
echo ' Подключение к базе данных прошло успешно.';
else
die(' База данных не найдена или отсутствует доступ.');
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$result=mysqli_query('SELECT * FROM `pisos`');
while ($row = mysqli_fetch_assoc($result))
{
   echo $row['group_number'];
}
?>

PHP7.0 报错：

Соединение установлено. Подключение к базе данных прошло успешно.PHP Warning:  mysqli_query() expects at least 2 parameters, 1 given in /var/www/admin/data/www/site/connect.php on line 15
PHP Warning:  mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, null given in /var/www/admin/data/www/site/connect.php on line 16

这个魔鬼想从我这里得到什么，我该如何解决？

我在 VK 中使用机器人来管理服务器。我想用subprocess.check_output这个。但是，如果您传递一个包含多个单词的命令，例如 df -h，则会引发错误。uptime、reboot、ifconfig 等命令工作正常。这是我的代码：

command="df -h"
res=subprocess.check_output(command)
output=str(res)

如何执行包含多个单词的命令？
