Question

This is the php/html table output

监考列是我希望mysql db中的行填满但输出不断重复相同名称的地方。我想要的是输出应该是这样的先生A. B先生 C先生 D先生先生A. B先生 C先生 D先生如果我们在数据库中只有4个名字（即按ASC顺序列出名称并一次又一次地重复）。这是我的php / html

<table class="table table-bordered table-hover table-striped">
    <caption>Timetable with number of students</caption>
         <thead>
              <tr>
                <th>#</th>
                <th>No. Students</th>
                <th>Course</th>
                <th>Date</th>
                <th>Start Time</th>
                <th>End Time</th>
                <th>Venue</th>
                <th>Duration</th>
                <th>Invigilator</th>
                <!-- <th>Edit/Del</th> -->
              </tr>
          </thead>
          <tbody>
                <?php
                    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
                    extract($row);
                    include('includes/shuffle.php');
                    while ($snm = mysqli_fetch_array($results, MYSQLI_ASSOC)) {
                    $snm1 = $snm["snm_pdo"];
                ?>
           <tr>
           <?php echo "<td>{$id_pdo}</td>" ?>
           <?php echo "<td>{$snb_pdo}</td>" ?>
           <?php echo "<td>{$cos_pdo}</td>" ?>
           <?php echo "<td>{$dat_pdo}</td>" ?>
           <?php echo "<td>{$starttim_pdo}</td>" ?>
           <?php echo "<td>{$endtim_pdo}</td>" ?>
           <?php echo "<td>{$ven_pdo}</td>" ?>
           <?php echo "<td>{$dur_pdo}</td>" ?>
           <?php echo "<td>{$snm1}</td>" ?>

            </tr>
         <?php
                    }
                    }
                ?>

这是我收录的shuffle.php

<?php  
    $con=mysqli_connect("localhost", "root", "", "timetable");
    if(!$con){
        die("Bros db no wan connect o" .mysqli_connect_error());
    }       

$query = "SELECT snm_pdo FROM staff_list ORDER BY snm_pdo ASC, RAND() LIMIT 3";
$results = mysqli_query($con, $query);mysqli_close($con);?>

This is the structure of the 2nd table(courses) 这是table_courses的查询这是在data.inc_course.php里面。

class Data {

// database connection and table name
private $conn;
private $table_name = "courses";
// private $table_name2 = "staff_list";
// object properties
public $id;
public $snb;
public $cos;
public $dat;
public $starttim;
public $endtim;
public $ven;
public $dur;
public function __construct($db){
    $this->conn = $db;
}

//阅读产品

    function readAll($page, $from_record_num, $records_per_page){
        $query = "SELECT 
                    *
                FROM 
                    " . $this->table_name . "
                ORDER BY 
                    id_pdo ASC 
                LIMIT 
                    {$from_record_num}, {$records_per_page}";
        $stmt = $this->conn->prepare( $query );
        $stmt->execute();
        return $stmt;
    }
}

然后在我的index.php页面中我有了这个

<?php
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$records_per_page = 5;
$from_record_num = ($records_per_page * $page) - $records_per_page;
include_once 'includes/config.php';
include_once 'includes/data.inc_course.php';
include 'includes/shuffle2.php';
$database = new Config();
$db = $database->getConnection();
$product = new Data($db);
$stmt = $product->readAll($page, $from_record_num, $records_per_page);
$num = $stmt->rowCount();
?>
<?php include('includes/header.php'); 
$output1 = "
    <body>
        <div id='wrapper'>";
        echo $output1;
       include('includes/nav.php');
$output2 = "
       <!-- Page Content -->

这是用于staff_list表查询的文件shuffle2.php

<?php  
    define('dbname', 'timetable');
    define('dbuserid', 'root');
    define('dbpasswd', '');
    define('dbhost', 'localhost');
    define('dbport', '3306');
    define('dbsocket', '');
    define('LBRK','<br />');

    // Connect to database
    $mysqli = new mysqli(dbhost, dbuserid, dbpasswd, dbname, dbport, dbsocket);
    if ($mysqli->connect_errno) {
        echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error.LBRK;
     exit(1);
    }

    $query1 = "SELECT snm_pdo FROM staff_list ORDER BY snm_pdo ASC, RAND() ";

    $results = $mysqli->query($query1);
    // if ($results===false) {
    //     // Query failed
    //     echo "Failed to read the database table ''<br />" .LBRK;
    //     exit(1);
    // }


    ?>
